Description

[0001] This case is a divisional application of the application with application number 202110729168.6, application date June 29, 2021, and invention name “Multi-band communication based on filter sharing”. Technical Field

[0002] The present disclosure relates generally to electronic devices, and more particularly to electronic devices that utilize radio frequency signals, transmitters, and receivers for wireless communications. Background Art

[0003] This section is intended to introduce the reader to various aspects of the art that may be related to various aspects of the present disclosure, which are described and / or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements should be read in this light, and not as admissions of prior art.

[0004] Transmitters and / or receivers are often included in various electronic devices, and more specifically, are often included in portable electronic communication devices, such as phones (e.g., mobile phones and cellular phones, cordless phones, personal assistant devices), computers (e.g., laptop computers, tablet computers), routers (e.g., Wi-Fi routers or modems), radios, televisions, or any of various other fixed or handheld devices to enable communication. In some electronic devices, the transmitter and receiver are combined to form a transceiver. For ease of discussion, a transceiver is discussed in the present disclosure, but it should be understood that the following description may apply to the transmitter and / or receiver alone (e.g., which may not be included in the transceiver).

[0005] Conventional electronic devices may include multiple sets of radio frequency filters that allow signals with desired frequencies to pass through and / or block signals with undesired frequencies. For example, a transmitter in an electronic device may include multiple transmit filters, each corresponding to transmit signals in a different frequency band, and a receiver in the electronic device may include multiple receive filters, each corresponding to receive signals in a specific frequency band. However, when a new frequency band is used for wireless communication, more radio frequency filters may be added to the electronic device to enable the electronic device to transmit and receive signals in the new frequency band, thereby taking up valuable space in the electronic device.

[0006] Furthermore, signal paths in conventional electronic devices may have a length as long as one-quarter wavelength of a signal transmitted or received via the signal path. While such a length may be useful for signals having a relatively narrow wavelength range, a one-quarter wavelength signal path may not be suitable for communication over a wider communication frequency band, such as fifth-generation (5G) networks, because 5G communications use frequencies that span a relatively large frequency band (e.g., between 24 gigahertz (GHz) and 48 GHz).

[0007] Various improvements to the above features may exist with respect to various aspects of the present invention. Other features may also be added to these various aspects. These improvements and additional features may exist alone or in any combination. For example, the various features associated with one or more of the illustrated embodiments discussed below may be incorporated into any of the above aspects of the present invention, alone or in any combination. The brief summary presented above is intended to familiarize the reader with the specific aspects and context of the disclosed embodiments and does not limit the claimed subject matter. Summary of the Invention

[0008] The following describes a summary of certain embodiments disclosed herein. It should be understood that these aspects are presented merely to provide the reader with a concise summary of these specific embodiments, and that these aspects are not intended to limit the scope of the present disclosure. In fact, the present disclosure may encompass a number of aspects that may not be described below.

[0009] An electronic device may include multiple RF filters, coupled to a transmitter and a receiver to enable sharing of the RF filters. Specifically, the electronic device may dynamically couple an antenna to a transmitter to transmit a transmit signal, and dynamically couple an antenna to a receiver to receive a receive signal. The transmitter and receiver may each be dynamically coupled to multiple RF filters, each of which may filter a different frequency band or frequency range. Furthermore, multiple RF filters may be dynamically coupled to a transmitter and / or receiver simultaneously to combine and filter additional frequency bands.

[0010] Generally speaking, the RF filter may include a first RF filter that allows signals in a first frequency band to pass through (for example, while blocking signals outside the first frequency band), allows signals in a second frequency band to pass through (for example, while blocking signals outside the second frequency band), and when the first RF filter and the second RF filter are coupled together, the first RF filter and the second RF filter allow signals in a third frequency band to pass through (for example, while blocking signals outside the third frequency band). For example, in the case of ultra-wideband frequencies, such as those used by fifth-generation (5G) networks (e.g., between 24 gigahertz (GHz) and 48 GHz), the RF filter may include a first frequency filter (e.g., in a first state) that allows signals in a first frequency band (e.g., between 24 GHz and 33 GHz) to pass through, a second frequency filter that, when combined with the first RF filter (e.g., in a second state), allows signals in a second frequency band (e.g., between 37 GHz and 43 GHz) to pass through, and a third frequency filter that, when combined with the first and second RF filters (e.g., in a third state), allows signals in a third frequency band (e.g., between 47 GHz and 49 GHz) to pass through. Note that while described with particular reference to 5G networks and frequency bands used in 5G networks, these filter-sharing systems and methods are applicable to various networks and frequency ranges, as long as the networks and / or frequency ranges are capable of sharing antenna circuitry. In fact, these systems and methods are applicable to antennas used to transmit and / or receive signals for 4G network communications, 3G network communications, 2G network communications, and the like.

[0011] By enabling both a transmitter and a receiver to use the same RF filter, and using the RF filters individually and in combination to filter different frequency bands, the number of filters in an electronic device can be significantly reduced, resulting in a smaller electronic device overall and / or enabling additional components to be included in the electronic device.

[0012] In practice, in some cases, the device may include a first filter coupled to an antenna and a second filter coupled to a first low-noise amplifier. The device may also include a third filter coupled to the second low-noise amplifier and a controller. The controller may transmit a transmit signal on a first frequency band by coupling the first filter to a power amplifier, decoupling the second filter from the antenna and the power amplifier, and decoupling the third filter from the antenna and the power amplifier based at least in part on one or more control signals indicating a first state. The controller may transmit a transmit signal on a second frequency band by coupling the first filter to the power amplifier, coupling the second filter to the antenna and the power amplifier, and decoupling the third filter from the antenna and the power amplifier based at least in part on one or more control signals indicating a second state. The controller may transmit a transmit signal on a third frequency band by coupling the first filter to the power amplifier, coupling the second filter to the antenna and the power amplifier, and coupling the third filter to the antenna and the power amplifier based at least in part on one or more control signals indicating a third state.

[0013] In some systems, an electronic device may include a first switch capable of coupling an antenna and a first filter to a first low-noise amplifier via a second filter. The electronic device may include a second switch capable of coupling the antenna and the first filter to a second low-noise amplifier via a third filter. The electronic device may also include a third switch capable of coupling the antenna and the first filter to a power amplifier. The electronic device may also include a controller. The electronic device may receive a receive signal in a first frequency band by activating the first switch to couple the first low-noise amplifier and the second filter to the antenna and the first filter, and deactivating the second and third switches to decouple the second low-noise amplifier, the third filter, and the power amplifier from the antenna. The electronic device may receive a receive signal in a second frequency band by activating the second switch to couple the second low-noise amplifier and the third filter to the antenna and the first filter, and deactivating the first and third switches to decouple the first low-noise amplifier, the second filter, and the power amplifier from the antenna. Furthermore, the electronic device may receive a receive signal in a third frequency band by activating the first and second switches to couple the first low-noise amplifier, the second filter, the second low-noise amplifier, and the third filter to the antenna and the first filter, and deactivating the third switch to decouple the power amplifier from the antenna.

[0014] In yet another example, a method may include receiving a frequency band parameter and a transmit or receive (TX / RX) parameter. The frequency band parameter and the TX / RX parameter may indicate an operating state of an antenna. The antenna may be coupled to a first filter and capable of being coupled to at least one of a second filter or a third filter. In response to the TX / RX parameter indicating a transmit operation, the method may include coupling the antenna to a power amplifier, wherein the power amplifier may amplify a transmit signal associated with the transmit operation. In response to the frequency band parameter indicating a first frequency band, the method may include decoupling the second filter and the third filter from the antenna. In response to the frequency band parameter indicating a second frequency band, the method may include coupling the second filter to the antenna and decoupling the third filter from the antenna. In response to the frequency band parameter indicating a third frequency band, the method may include coupling the second filter and the third filter to the antenna. In some cases, the method may include transmitting the transmit signal using the power amplifier and the antenna.

[0015] Various improvements to the above features may exist with respect to various aspects of the present invention. Other features may also be added to these various aspects. These improvements and additional features may exist alone or in any combination. For example, the various features associated with one or more of the illustrated embodiments discussed below may be incorporated into any of the above aspects of the present invention, alone or in any combination. The brief summary presented above is intended to familiarize the reader with the specific aspects and context of the disclosed embodiments and does not limit the claimed subject matter.

In some cases, the controller 20 may operate circuitry to input or output data generated by the electronic device 10. For example, the controller 20 may control and / or operate the memory 14, storage device 16, display 18, input structure 22, input / output (I / O interface) 24, network interface 26, transceiver 28, power supply 29, etc. to perform operations of the electronic device 10 and / or facilitate control of the operations of the electronic device. Specifically, the controller 20 may generate control signals for operating the transceiver 28 to transmit and / or receive data over one or more communication networks.

[0039] The input structures 22 of the electronic device 10 may enable a user to interact with the electronic device 10 (e.g., pressing a button to increase or decrease the volume level). As with the network interface 26, the I / O interface 24 may enable the electronic device 10 to interact with various other electronic devices. The network interface 26 may, for example, include one or more interfaces for a personal area network (PAN) such as a Network, Local Area Network (LAN) or Wireless Local Area Network (WLAN) such as 802.11x networks, and / or wide area networks (WANs) such as 3rd generation (3G) cellular networks, 4th generation (4G) cellular networks, long term evolution (LTE) cellular network, Long Term Evolution License Assisted Access (LTE-LAA) cellular network, 5th Generation (5G) cellular network, or New Radio (NR) cellular network.

For example, the keyboard and / or touchpad may facilitate user interaction with a user interface, GUI, and / or application interface displayed on the display 18.

[0042] Figure 3 A front view of a handheld device 10B is depicted, which represents one embodiment of an electronic device 10. The handheld device 10B may represent, for example, a portable telephone, a media player, a personal data organizer, a handheld gaming platform, or any combination of such devices. For example, the handheld device 10B may be a device available from Apple Inc.

[0044] Figure 4A front view of another handheld device 10C is depicted, which represents another embodiment of the electronic device 10. The handheld device 10C can represent, for example, a tablet computer, or one of various portable computing devices. For example, the handheld device 10C can be a tablet-sized embodiment of the electronic device 10, specifically, a tablet computer available from, for example, Apple Inc. (Cupertino, California). Type handheld device.

[0045] See also Figure 5 , the computer 10D can represent Figure 1 Another embodiment of the electronic device 10 is shown. The computer 10D may be any computer, such as a desktop computer, a server, or a laptop computer, but may also be a stand-alone media player or video game console. For example, the computer 10D may be a computer from Apple Inc. of Cupertino, California. or other similar devices. It should be noted that the computer 10D may also represent a personal computer (PC) from another manufacturer. The housing 36 may protect and enclose the internal components of the computer 10D, such as the display 18. In some embodiments, a user of the computer 10D may interact with the computer 10D using various peripheral input devices such as a keyboard 22A or a mouse 22B (e.g., input structures 22) that may be operatively coupled to the computer 10D.

[0046] Similarly, Figure 6 Depicted Figure 1 Another embodiment of the electronic device 10 is a wearable electronic device 10E. For example, the wearable electronic device 10E that can include the wristband 43 can be an Apple device manufactured by Apple, Inc. of Cupertino, California. However, in other embodiments, the wearable electronic device 10E may include any wearable electronic device, such as a wearable motion monitoring device (e.g., a pedometer, an accelerometer, a heart rate monitor), or other device from another manufacturer. The display 18 of the wearable electronic device 10E may include a display 18 (e.g., an LCD, an OLED display, an active matrix organic light emitting diode (AMOLED) display, etc.) and a touch screen version of the input structure 22, which may facilitate user interaction with the user interface of the wearable electronic device 10E. In some embodiments, as described above, each embodiment of the electronic device 10 (e.g., the laptop 10A, the handheld device 10B, the handheld device 10C, the computer 10D, and the wearable electronic device 10E) may include a transceiver 28.

[0047] Taking the above into consideration, Figure 7is a circuit diagram of at least a portion of transceiver 28 that operates to transmit and / or receive radio frequency (RF) signals using transmitter circuitry 50, receiver circuitry 51, and circuitry (shared circuitry 52) shared by transmitter circuitry 50 and receiver circuitry 51, in accordance with an embodiment of the present disclosure. Transmitter circuitry 50 may include transmitter processing circuitry 54 that processes a transmit signal and sends the processed transmit signal to power amplifier 56 for amplification prior to transmission via antenna 57. Receiver circuitry 51 receives a signal from antenna 57 as part of a receive operation and may amplify the received signal using one or more low noise amplifiers (LNAs) 60 (60A, 60B) before sending the signal to receiver processing circuitry 58 (58A, 58B) for processing.

[0048] One or more LNAs 60 can increase the amplitude of a signal without increasing the noise of the signal. For example, LNAs 60A and 60B can each receive a receive signal from antenna 57, depending on the receive mode being used by transceiver 28, and increase the amplitude of the signal without increasing the noise of the receive signal. Although two LNAs 60 are shown, it should be understood that any number of LNAs, such as two, three, four, or more, can be implemented in transceiver 28 to amplify any suitable number of frequency bands. In the illustrated embodiment, LNA 60A can process relatively low frequencies (e.g., corresponding to a low-band low-noise amplifier or a mid-band low-noise amplifier), and LNA 60B can process relatively high frequencies (e.g., corresponding to a high-band low-noise amplifier). In some embodiments, controller 20 or other circuitry (not shown) of receiver circuitry 51 can adjust the power provided to LNAs 60A and 60B based on average power tracking or envelope tracking of the modified signal.

[0049] The received signals output from LNAs 60A, 60B or other circuits of receiver circuitry 51 may be transmitted to receiver processing circuitry 58 for additional processing, such as by filtering and / or demodulating the signals. Receiver processing circuitry 58 may include any suitable hardware or software to perform various signal improvement or signal analysis operations on the received signals from antenna 57. For example, receiver processing circuitry 58 may include an analog-to-digital converter, additional filtering circuitry, phase shifting circuitry (e.g., a 180-degree phase shifter), etc.

[0050] Shared circuit 52 can be used by both transmitter circuit 50 for transmitting signals and receiver circuit 51 for receiving signals. Thus, shared circuit 52 includes antenna 57, as well as radio circuit filtering circuitry that can allow signals of desired frequencies to pass or block signals of undesired frequencies. Specifically, transmitter circuit 50 can include switching circuitry 62 (e.g., switch 62A) that enables transmitter circuit 50 to couple to antenna 57 for transmitting signals and decouple from antenna 57 (e.g., when receiver circuit 51 is receiving signals). Similarly, receiver circuit 51 can include switching circuitry 62 (e.g., switches 62F, 62G) that enables receiver circuit 51 to couple to antenna 57 for receiving signals and decouple from antenna 57 (e.g., when transmitter circuit 50 is transmitting signals).

[0051] Specifically, when turned on (e.g., activated to enable current flow) via control signal S1, power amplifier 56 can be coupled to antenna 57 via switch 62A. Switch 62A and / or any of the switch circuits 62 discussed herein (e.g., 62B, 62C, 62D, 62E, 62F, 62G) can be any suitable transistor or switching device, such as a metal oxide semiconductor field effect transistor (MOSFET), an insulated gate bipolar transistor (IGBT), etc., and can each be controlled by a corresponding control signal S (e.g., S1, S2, S3, S4, S5). Controller 20 can transmit a control signal (e.g., control signal S2) having a voltage value suitable for causing the terminals of the corresponding transistors of switch circuit 62 to conduct, thereby turning on or activating the switch circuit 62, respectively. When the voltage value is not suitable for causing the terminals to conduct, the switch circuit 62 can be said to be deactivated or turned off.

[0052] Antenna 57 may also be coupled to filter 64. Filter 64 may remove (e.g., filter, attenuate to zero amplitude, or attenuate to a lower amplitude) signals characterized by frequencies below or above a threshold frequency range. In this way, filter 64 may improve RF signal quality (e.g., reduce noise, isolate desired frequencies from undesired frequencies). Filter 64 is shown as including inductor 66 coupled in parallel with capacitor 68. However, it should be understood that any combination of filtering circuits and / or attenuation circuits may be used to pass the desired frequency range. For example, any suitable filter or attenuation circuit may be used in place of or in addition to filter 64, and filter 64 may be considered a high-pass filter, a band-pass filter, etc. Shared circuit 52 may also include additional RF filtering circuits (e.g., filters 70A, 70B) that may individually filter signals in different RF bands and, when combined, filter signals in additional RF bands.

[0053] For example, filter 64 alone can be used to pass transmitted or received signals within a first frequency range (e.g., between 24 gigahertz (GHz) and 33 GHz) and block signals outside the first frequency range. When filter 64 is combined with filter 70A, such as through at least switch 62B, the combination of filtering circuits can be used to pass transmitted or received signals within a second frequency range (e.g., between 37 GHz and 43 GHz) and block signals outside the second frequency range. Furthermore, when filter 64 is combined with filter 70A and filter 70B, such as through switches 62B and 62C, the combination of filtering circuits can be used to pass transmitted or received signals within a third frequency range (e.g., 48 GHz, between 47 GHz and 49 GHz) and block signals outside the third frequency range.

[0054] By sharing filtering circuitry (e.g., filters, circuitry characterized by impedance) between transmit and receive operations (e.g., by turning switches 62A, 62F, 62G on and off to couple transmitter circuitry 50 or receiver circuitry 51 to shared circuitry 52), and selecting different filters 64, 70A, 70B based on the desired filtering frequency (e.g., by turning switches 62B, 62C, 62D, 62E on and off), transceiver 28 can communicate with signals having a relatively wide range of frequencies. These ranges may include, for example, frequencies within a threshold range of these frequencies, such as 1 GHz, 500 megahertz (MHz), 100 MHz, 10 MHz, 100 Hertz (Hz), etc. Note that in this disclosure, three filtering circuits are used to enable transceiver 28 to handle three different frequency ranges. However, it should be understood that different filters, a different number of filters, and / or different impedances may be used to enable transceiver 28 to handle different frequency ranges (e.g., frequency ranges of different frequencies, a different number of frequency ranges).

[0055] To help detail the launch operation, Figure 8 is an embodiment according to the present disclosure and Figure 14 The operation of at least block 122 corresponds to operating in a first transmit mode to transmit a signal (e.g., transmit signal 72) having a first frequency range (e.g., approximately between 24 GHz and 33 GHz). Figure 7 1 is a circuit diagram of transceiver 28. It should be noted that, as shown, when a switch is represented by a solid line, the switch is on or closed (e.g., capable of conducting), and when a switch is represented by a dashed line, the switch is off or disconnected (e.g., not conducting). The above-mentioned signals can be processed by transceiver 28. When in the first transmit mode, transceiver 28 can process signals having frequencies within a first frequency range.

[0056] Specifically, filter 64 may pass frequencies of transmit signal 72 within a first frequency range while blocking frequencies of transmit signal 72 outside the first frequency range. To this end, controller 20 of processor 12 may close switch 62A to couple transmitter circuit 50 to filter 64 and antenna 57 via power amplifier 56. Controller 20 may also close switch 62B to decouple filter 70A, LNA 60A, and receiver processing circuit 58A from antenna 57. Thus, transmit signal 72 may not be filtered by filter 70A and may be isolated from LNA 60A and receiver processing circuit 58A. Similarly, controller 20 may further close switch 62C to decouple filter 70B, LNA 60B, and receiver processing circuit 58B from antenna 57. Thus, transmit signal 72 may not be filtered by filter 70B and may be isolated from LNA 60B and receiver processing circuit 58B. In addition, the controller 20 may operate the switch 62D to be OFF, the switch 62E to be OFF, the switch 62F to be OFF, and the switch 62G to be OFF.

[0057] When the switch is operated in this configuration, the transceiver 28 uses filter 64 to process the transmit signal 72 output from the transmitter processing circuit 54 for transmission, but does not use filter 70A and filter 70B. In addition, the transmit signal 72 is isolated from the receiver circuit 51. To filter frequencies of the transmit signal 72 from a frequency band other than the first frequency band, an additional filter (e.g., filter 70A) may be combined with filter 64 rather than using a completely different filter or filter bank from filter 64. This is particularly advantageous in that Figure 9 Shown in.

[0058] Figure 9 is an embodiment according to the present disclosure and Figure 14 The operation of at least block 126 corresponds to operating in a second transmit mode to transmit a signal (e.g., transmit signal 72) having a second frequency range (e.g., approximately between 37 GHz and 43 GHz). Figure 7 2. Circuit diagram of transceiver 28. The combination of filter 64 and filter 70A allows frequencies of transmit signal 72 within the second frequency range to pass through to antenna 57 while blocking frequencies of transmit signal 72 outside the second frequency range.

[0059] To this end, controller 20 of processor 12 may close switch 62A to couple transmitter circuit 50 to filter 64 and antenna 57 via power amplifier 56. Controller 20 may also close switch 62B and switch 62D to couple filter 70A to filter 64, antenna 57, and power amplifier 56. However, controller 20 may close switch 62F to decouple LNA 60A and receiver processing circuit 58A from antenna 57. Thus, transmit signal 72 may be filtered by filter 70A in conjunction with filter 64 and may be isolated from LNA 60A and receiver processing circuit 58A. Controller 20 may further close switch 62C to decouple filter 70B, LNA 60B, and receiver processing circuit 58B from antenna 57. Thus, transmit signal 72 may not be filtered by filter 70B and may be isolated from LNA 60B and receiver processing circuit 58B. Furthermore, controller 20 may operate switch 62E to be closed, switch 62F to be closed, and switch 62G to be closed.

[0060] When the switch is operated in this configuration, the transceiver 28 uses the filter 64 and the filter 70A to process the transmit signal 72 output from the transmitter processing circuit 54 for transmission, but does not use the filter 70B. In addition, the transmit signal 72 is isolated from the receiver circuit 51. In order to filter the frequencies of the transmit signal 72 from different frequencies than the first and second frequency bands, an additional filter (e.g., filter 70B) may be combined with the filter 64 and the filter 70A, rather than using a completely different filter or filter bank than the filter 64. This is in Figure 10 Shown in.

[0061] Figure 10 is an embodiment according to the present disclosure and Figure 14 The operation of at least block 128 corresponds to operating in a third transmit mode to transmit a signal (e.g., transmit signal 72) having a third frequency range (e.g., approximately 48 GHz, between approximately 47 GHz and 49 GHz). Figure 7 2. The combination of filter 64, filter 70A, and filter 70B allows frequencies of transmit signal 72 within the third frequency range to pass while blocking frequencies of transmit signal 72 outside the second frequency range from passing to antenna 57.

[0062] To this end, controller 20 of processor 12 may turn on switch 62A to couple transmitter circuit 50 to filter 64 and antenna 57 via power amplifier 56. Controller 20 may turn on switch 62B and switch 62D to couple filter 70A to filter 64, antenna 57, and power amplifier 56. Controller 20 may also turn on switch 62C and switch 62E to couple filter 70B to filter 64, filter 70A, antenna 57, and power amplifier 56. However, controller 20 may turn off switch 62F to decouple LNA 60A and receiver processing circuit 58A from antenna 57, and may turn off switch 62G to decouple LNA 60B and receiver processing circuit 58B from antenna 57. Thus, transmit signal 72 may be filtered by filters 70A and 70B and may be isolated from LNA 60A, LNA 60B, receiver processing circuit 58A, and receiver processing circuit 58B.

[0063] When the switch is operated in this configuration, the transceiver 28 uses the filter 64, the filter 70A, and the filter 70B to process the transmit signal 72 transmitted from the transmitter processing circuit 54 for transmission. In addition, the transmit signal 72 is isolated from the receiver circuit 51. In order to filter the frequencies of the received signal other than the transmit signal (e.g., the transmit signal 72), the filter 70A can be combined with the filter 64, rather than using a completely different filter or filter bank from the filter 64. This is in Figure 11 Shown in.

[0064] Specifically, transceiver 28 is operable to transmit a transmit signal 72 after being amplified by power amplifier 56. However, in some cases, transceiver 28 may be used to receive one or more RF signals. Advantageously, the same filters 64, 70A, 70B of shared circuitry 52 used by transmitter circuitry 50 can be reused by receiver circuitry 51 to filter the same or similar frequency bands. In this way, space reserved for receiver filtering circuitry separate from the transmitter filtering circuitry can be reclaimed or used for additional components in electronic device 10.

[0065] For example, Figure 11 According to the embodiments of the present disclosure and with Figure 14 At least block 134 corresponds to a circuit diagram of transceiver 28 operating in a first receive mode. The combination of filter 64 and filter 70A may allow frequencies of received signal 100 within a first frequency range (e.g., between 24 GHz and 33 GHz) to pass to receiver processing circuitry 58A while blocking frequencies of received signal 100 outside the first frequency range.

[0066] To this end, controller 20 of processor 12 may close switch 62A to decouple transmitter circuit 50 from filter 64 and antenna 57 via power amplifier 56. Controller 20 may close switch 62B and may close switch 62D to couple filter 70A to filter 64, antenna 57, and LNA 60A. However, controller 20 may close switches 62C and 62E to decouple filter 70B from antenna 57. Controller 20 may close switch 62G to decouple LNA 60B and receiver processing circuit 58B from antenna 57. As a result, received signal 100 may be filtered by filter 70A in conjunction with filter 64 but not by filter 70B, and may be isolated from LNA 60B and receiver processing circuit 58B.

[0067] When the switch is operated in this configuration, transceiver 28 processes receive signal 100 received at antenna 57 using filter 64 and filter 70A, but not filter 70B. In addition, receive signal 100 is isolated from transmitter circuitry 50. Rather than using a completely different filter or filter bank than filter 64, an additional filter (e.g., filter 70B) may be combined with filter 64 instead of filter 70A to filter frequencies from receive signal 100 other than the first frequency band. This is particularly advantageous in that the filter 70B may be used to filter frequencies from receive signal 100 other than the first frequency band. Figure 12 Shown in.

[0068] The controller 20 can also operate the transceiver 28 in a second receive mode to receive the receive signal 100 using a second frequency range. For example, Figure 12 According to the embodiments of the present disclosure and with Figure 14 138 corresponds to a circuit diagram of transceiver 28 operating in a second receive mode. The combination of filter 64 and filter 70A may allow frequencies of received signal 100 within a second frequency range (e.g., between 37 GHz and 43 GHz) to pass to receiver processing circuitry 58B while blocking frequencies of received signal 100 outside the second frequency range.

[0069] To this end, controller 20 of processor 12 may close switch 62A to decouple transmitter circuit 50 from filter 64 and antenna 57 via power amplifier 56. Controller 20 may close switch 62C and may close switch 62E to couple filter 70B to filter 64, antenna 57, and LNA 60B. Controller 20 may close switches 62B and 62D to decouple filter 70A from antenna 57. Controller 20 may close switch 62F to decouple LNA 60A and receiver processing circuit 58A from antenna 57. Thus, received signal 100 may be filtered by filter 70B in conjunction with filter 64 but not by filter 70A, and may be isolated from LNA 60A and receiver processing circuit 58A.

[0070] When the switch is operated in this configuration, transceiver 28 uses filter 64 and filter 70B to process receive signal 100 received at antenna 57, but does not use filter 70A. In addition, receive signal 100 is isolated from transmitter circuit 50. To filter frequencies of receive signal 100 from frequencies other than the first or second frequency bands, filter 70B may be combined with filter 64 and filter 70A, rather than using a separate filter or filter bank from filter 64. This is particularly advantageous in that Figure 13 Shown in.

[0071] Figure 13 According to the embodiments of the present disclosure and with Figure 14 140 corresponds to a circuit diagram of transceiver 28 operating in a third receive mode. The combination of filter 64, filter 70A, and filter 70B may allow frequencies of receive signal 100 within a third frequency range (e.g., approximately 48 GHz, between approximately 47 GHz and 49 GHz) to pass to receiver processing circuitry 58B while blocking frequencies of receive signal 100 outside the third frequency range.

[0072] To this end, controller 20 of processor 12 may close switch 62A to decouple transmitter circuit 50 from filter 64 and antenna 57 via power amplifier 56. Controller 20 may close switch 62C and close switch 62E to couple filter 70B to filter 64, antenna 57, and LNA 60B. Controller 20 may close switch 62B and switch 62D to couple filter 70A to antenna 57, filter 64, and filter 70B. Controller 20 may close switch 62F to decouple LNA 60A and receiver processing circuit 58A from antenna 57. Thus, receive signal 100 may be filtered by filter 70B in conjunction with filter 64 and filter 70A, and may be isolated from LNA 60A and receiver processing circuit 58A.

[0073] When the switches are operated in this configuration, transceiver 28 uses filter 64, filter 70A, and filter 70B to process receive signal 100 received at antenna 57. Furthermore, receive signal 100 is isolated from transmitter circuit 50. For ease of description, the various operating modes of transceiver 28 are summarized in Table 1 below. Note that Table 1 summarizes the relative states of a particular switch circuit 62 and how the combination of switch circuit 62 operations corresponds to the various operating modes of transceiver 28, where switch 62A corresponds to S1, switch 62B corresponds to S2, switch 62C corresponds to S3, switch 62D corresponds to S4, switch 62E corresponds to S5, switch 62F corresponds to S6, and switch 62G corresponds to S7. In some cases, Table 1 also summarizes the states of control signals (e.g., control signals S1, S2, S3, S4, S5, S6, S7) provided to switch circuit 62. As shown in the figure, the control signal S as a logic high "ON" signal activates (e.g., turns on) the corresponding switch circuit 62 to close the circuit, while the control signal S as a logic low "OFF" signal deactivates (e.g., turns off) the corresponding switch circuit 62 to open the circuit.

[0075]

[0076] To further clarify the operation of the transceiver 28, Figure 14 1 is a flow chart of a method 110 for operating an electronic device 10 to transmit and / or receive RF signals using a frequency range (e.g., between approximately 24 GHz and 33 GHz), a second frequency range (e.g., between approximately 37 GHz and 43 GHz), and / or a third frequency range (e.g., between approximately 47 GHz and 49 GHz, approximately 48 GHz). It should be noted that, although shown in a particular order, the blocks of method 110 can be executed in any suitable order. As described herein, method 110 is described as being executed by controller 20, however, it should be understood that any suitable processing and / or control circuitry may perform some or all of the operations of method 110, such as one or more processors in processor 12.

[0077] At block 112, the controller 20 may receive frequency band parameters and transmit or receive (TX / RX) parameters. These parameters may be received in the same or different data packets. In some cases, the controller 20 may receive frequency band parameters and / or TX / RX parameters by reading a register, such as a configuration register, or the state of other suitable types of memory or storage elements of the electronic device 10. The frequency band parameters may indicate which frequency range a portion of the transceiver 28 will be programmed to use. The TX / RX parameters may indicate whether that portion of the transceiver 28 will be programmed to transmit and / or receive signals. Note that in some embodiments, the frequency band parameters may explicitly indicate a first frequency range or a second frequency range. If no indication is present, the controller 20 may default to controlling the transceiver 28 to operate using a third frequency range. In some cases, the controller 20 may default to one of the other frequency ranges and / or one of the other operating modes.

[0078] After receiving and / or accessing the frequency band parameters and / or TX / RX parameters, the controller 20 may determine whether the TX / RX parameters indicate a transmit operation or a receive operation at block 114. The controller 20 may interpret one or more states of the TX / RX parameters to determine whether the parameters indicate a transmit operation or a receive operation.

[0079] When the TX / RX parameter indicates that the current operation is associated with a transmit (TX) operation, the controller 20 may set the control signal state of the switch 62A at block 116 to couple the antenna 57 and the filter 64 to the power amplifier 56. At block 120, the controller 20 may determine whether the frequency band parameter indicates a first frequency range. When the frequency band parameter indicates the first frequency range, the controller 20 may set the control signal state of the switch 62B at block 122 to decouple the filter 70A from the antenna 57 and the filter 64, and may set the control signal state of the switch 62C to decouple the filter 70B from the antenna 57 and the filter 64 using the switch 62C.

[0080] When the frequency band parameter does not indicate the first frequency range, the controller 20 may determine whether the frequency band parameter indicates a second frequency range at block 124. When the frequency band parameter indicates the second frequency range, the controller 20 may set the control signal states of switches 62B and 62D to couple filter 70A to antenna 57 and filter 64, and may set the control signal state of switch 62C to decouple filter 70B from antenna 57 and filter 64 at block 126. In some embodiments, when the frequency band parameter indicates the second frequency range, the controller 20 may set the control signal state of switch 62D to isolate LNA 60A from antenna 57 and filter 64. The controller 20 may also set the control signal states of switches 62F and 62G to OFF to decouple LNAs 60A, 60B from antenna 57 and filter 64.

[0081] When the frequency band parameter does not indicate the first frequency range or the second frequency range, controller 20 may default to operation in the third transmit mode at block 128 and, therefore, may set the control signal states of switch 62B and switch 62D to couple filter 70A to antenna 57 and filter 64, and may set the control signal states of switch 62C and switch 62E to couple filter 70B to antenna 57 and filter 64. Controller 20 may set the control signal state of switch 62F to decouple LNA 60A from antenna 57 during the third transmit mode, and may set the control signal state of switch 62G to decouple LNA 60B from antenna 57 during the third transmit mode.

[0082] After the various filters 70 are coupled or decoupled from the antenna 57 and / or the filter 64 according to the above blocks, the transmit signal 72 may be transmitted from the power amplifier 56 to the antenna 57 at block 130. The controller 20 may initiate the transmission of the transmit signal 72, and / or the transmission of the transmit signal 72 may occur automatically in view of the time at which the transceiver 28 is configured.

[0083] Referring back to block 114, when the TX / RX parameter indicates receive operation, the controller 20 may set the control signal state of switch 62A at block 118 to decouple the power amplifier 56 from the antenna 57 and from the filter 64. After, before, or simultaneously with setting the control signal state to decouple the power amplifier 56, the controller 20 may determine whether the frequency band parameter indicates a first frequency range at block 132. When the frequency band parameter indicates the first frequency range, the controller 20 may set the control signal state of switches 62B and 62F at block 134 to couple the filter 70A to the antenna 57 and the filter 64. The controller 20 may also set the control signal state of switch 62C to decouple the filter 70B and the LNA 60B from the antenna 57 and the filter 64, and set the control signal state of switch 62D to allow the transmit signal to pass through to the LNA 60A.

[0084] When the frequency band parameter does not indicate the first frequency range, the controller 20 may determine whether the frequency band parameter indicates a second frequency range at block 136. When the frequency band parameter indicates the second frequency range, the controller 20 may set the control signal state of switch 62C to couple filter 70B and LNA 60B to antenna 57 and filter 64 at block 138. The controller 20 may set the control signal state of switch 62E to allow received signal 100 to be transmitted from antenna 57 to LNA 60A. The controller 20 may also set the control signal state of switch 62B and switch 62D to decouple filter 70A and LNA 60A from antenna 57 and filter 64.

[0085] When the frequency band parameter does not indicate the first frequency range and the second frequency range, controller 20 may default to using the third frequency range at block 140 and may set the control signal states of switch 62B and switch 62D to couple filter 70A to antenna 57 and filter 64 without additionally coupling LNA 60A to antenna 57 and filter 64. Controller 20 also sets the control signal states of switch 62C and switch 62E to couple filter 70B and LNA 60B to antenna 57 and / or high-pass filter 64 by activating switch 62C and not activating switch 62E.

[0086] After coupling or decoupling the various filters 70 to the antenna 57 and / or the high pass filter 64 according to the blocks described above, the controller 20 may receive the receive signal 100 via the antenna 57 at block 142 .

[0087] Once the transceiver 28 receives the receive signal 100 or transmits the transmit signal 72, the controller 20 may determine at block 144 whether a subsequent communication operation is to be performed. To this end, the controller 20 may, for example, refer to a communication configuration that defines a transmit mode and / or a receive mode for the electronic device 10. In some cases, the controller 20 may read a status register that can indicate whether a subsequent communication operation is to occur. If, at block 144, the controller 20 determines that a subsequent communication operation is to occur, the controller 20 may repeat execution of the method 110, such as by returning to block 112.

[0088] However, in some cases, if the controller 20 determines that the subsequent operation is not to be performed at this time, then at block 146, the controller 20 may reduce (e.g., power gate) or eliminate (e.g., remove) the power provided to at least a portion of the transceiver 28, such as the power amplifier 56, and / or may cease the communication operation. To this end, the power provided to a portion of the electronic device 10 (e.g., the power provided to the transceiver 28) may be completely reduced or removed between communication operations. In this way, the method 110 may enable the electronic device 10 to transmit or receive signals of different frequency bands by sharing and reusing the RF filters 64, 70A, 70B. As a result, the number of RF filters in the electronic device 10 may be significantly reduced, resulting in a smaller overall electronic device and / or enabling additional components to be included in the electronic device 10. Furthermore, the method 110 and electronic device 10 described herein are applicable to transmitting and receiving signals of various wavelengths (e.g., relatively narrow wavelengths, intermediate wavelengths, wide wavelengths, ultra-wide wavelengths), and therefore do not suffer from the drawbacks of a quarter-wavelength signal path.

[0089] Please note that reference should be made again. Figure 9As an example, turning on switch 62D may also redirect leakage current to ground (e.g., a reference voltage) that might otherwise be transmitted to receiver processing circuitry 58A when filter 70A is combined with filter 64. Similarly, turning on switch 62E may redirect leakage current to ground rather than transmitting the leakage current to receiver processing circuitry 58B during transmit operations.

[0090] The technical effects of the present disclosure include systems and methods for operating a transceiver circuit to transmit and / or receive signals within various frequency ranges by sharing and reusing radio frequency filters. Specifically, a transmitter or receiver of the transceiver circuit can be selectively coupled to or decoupled from an antenna of the transceiver circuit. Additionally, the radio frequency filters can be coupled and / or decoupled to the antenna individually or collectively to filter different frequencies in the transmitted or received signal.
