Description
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to U.S. patent application No. 18 / 092,683, filed on January 3, 2023, which is incorporated herein by reference in its entirety. Technical Field
[0003] The present disclosure relates to packaging technology, and more particularly to the integration of radio frequency front ends for size reduction and performance improvement. Background Art
[0004] Generally speaking, RF devices may include packages, such as system-level packages. A system-level package combines a substrate, a die, multiple integrated circuits, and / or passive devices into a single package. The system-level package may be made of a semiconductor material, such as silicon. For example, the substrate and the die may include silicon on which the integrated circuit is manufactured. The substrate, the die, and the device may be coupled by bonding to leads of the package or by solder joints (e.g., solder balls or pads). By way of example, the die may be stacked (e.g., in a two and a half dimensional (2.5D) or three dimensional (3D) stacked structure) to combine the die into the same package rather than placing it on a printed circuit board. In some cases, the system-level package may also include multiple packages that are stacked (e.g., using stacked packaging technology) or have a die embedded in a substrate.
[0005] By way of example, an RF device that supports communications over frequencies in the millimeter wave (mmWave) range typically provides support at frequencies at or near 30 GHz. In some cases, an RF device may also support mmWave communications over additional mmWave bands for wider frequency coverage (such as for 30 GHz-300 GHz). Multiple antennas (e.g., antenna arrays) of an RF device may transmit signals that are combined to form beams (e.g., beamformed signals) for communicating over mmWave. In order to achieve consistent coverage (e.g., from a base station associated with mmWave communications), the RF device may include multiple antenna arrays positioned in different parts of the RF device. However, assembling these multiple antenna arrays in a system-in-package of the RF device may take up space and undesirably increase the size of the RF device. Summary of the Invention

[0040] Figure 2 yes Figure 1A FIG2 is a schematic diagram of a system-in-package 200 for an electronic device 100. Although the depicted embodiment shows multiple panels on different sides and on the same layer of the electronic device 100, the system described herein is also applicable to stacked panels, such as a three-dimensional (3D) stack of printed circuit boards. That is, one or more of the panels can be positioned on top of or below one or more other panels. In addition, at least one of the panels can include a redistribution printed circuit board that provides connections between the panels coupled to the redistribution printed circuit board.
[0041] In the depicted embodiment, the system-in-package 200 includes packaging for a front glass panel 232 (e.g., a front surface panel or cover glass panel), a main logic board 233 having a back glass panel 234, a left side panel 236, and a right side panel 238. Although the following description describes panels 232, 234, 236, and 238 as being disposed on the front, back, left, and right sides of the electronic device 100, respectively, which represents a particular embodiment, the system-in-package 200 described herein may additionally or alternatively include panels disposed at other areas of the electronic device 100 that may include one or more antennas. For example, the system-in-package 200 may also include a top-side panel or a bottom-side panel disposed on the top or bottom of the electronic device 100, respectively, adjacent to the left side panel 236 and the right side panel 238. Furthermore, although the following description describes one antenna array, which represents a particular embodiment, the system-in-package 200 described herein may additionally or alternatively include multiple antenna arrays.
[0042] The main logic board 233 may include a rear glass panel 234, a power management circuit 239, a transceiver 110, an antenna array selector 237, an application processor 235, and a first antenna array 250A. The application processor 235 may be coupled to the power management circuit 239 to control power functions, including power functions related to wireless communication. The power management circuit 239 may include one or more integrated circuits and control the power provided to the main logic board 233 and / or components of the electronic device 100 (including, for example, the transceiver 110 and / or the antenna array selector 237) (e.g., via the processor 102). By way of example, the power management circuit 239 may control the following processes: supplying power to the main logic board 233, providing power to components on or coupled to the main logic board 233, panels 232, 234, 236, and / or 238; selecting power; power sequencing; converting direct current (DC) for specific power-related functions; charging the battery of the electronic device 100, etc.
[0043] As shown, the transceiver 110 may be coupled to an antenna array selector 237, a first antenna array 250A of the rear glass panel 234, and components of the front glass panel 232. The antenna array 250A includes a plurality of antennas that transmit and / or receive wireless signals and may form a directional beam using the signals transmitted by each of the antennas. Figure 1AAs discussed, the transceiver 110 is a device that includes a transmitter and a receiver in a single package and can use the antennas in the first antenna array 250A to send and receive data via wireless signals conveyed at a specific radio frequency. Specifically, the transceiver 110 may include a transmitter and a receiver that include components that facilitate the transmission and reception of wireless signals, such as those components that transmit and receive between electronic devices 100 using mmWave communication technology or any other suitable communication protocol. When communicating on mmWave frequencies, the electronic device 100 may utilize beamforming technology to form a directional beam, as previously mentioned. The transmitter of the transceiver 110 may include one or more phase shifters, a transmitter power detector, and a power amplifier. The transmitter phase shifter can modulate (e.g., shift the phase of) the transmit signal (e.g., the wireless signal transmitted from the antennas in the first antenna array 250A) and can form a beam that can be steered in a specific direction (e.g., a directional beam), such as toward another electronic device (e.g., another electronic device 100 or a base station). The power amplifier can amplify the power level of the transmit signal. Specifically, a power amplifier supply voltage may be supplied to the power amplifier to control the amount of amplification provided by the power amplifier (e.g., to increase or decrease amplification, which may affect the antenna gain at the corresponding antenna). The transmitter power detector may measure the power of transmit signals transmitted from the antennas in the first antenna array 250A.
[0044] The receiver of the transceiver 110 may include one or more receiver phase shifters, a low-noise amplifier, and a receiver power detector. The receiver phase shifter and receiver power detector may operate similarly to the transmitter phase shifter and transmitter power detector. The low-noise amplifier may amplify the power level of a received signal (e.g., a wireless signal received at an antenna in the first antenna array 250A). Additional components in the transmitter and / or receiver may include, but are not limited to, filters, mixers, and / or attenuators.
[0045] The antenna array selector 237, which may be coupled to the transceiver 110, may activate or enable communications from one or more of the antennas in the antenna array 250 (such as the first antenna array 250A). For example, based on data throughput, the antenna array selector 237 may selectively enable multiple antennas to accommodate data throughput. As shown, the first antenna array 250A is disposed at the rear glass panel 234. The rear glass panel 234 may include one or more printed circuit boards coupled to the rear surface (e.g., rear glass) of the electronic device 100. As shown, the first antenna array 250A may include an M×N array of first frequency band antennas 251 (Band 1), second frequency band antennas 253 (Band 2), and third frequency band antennas 255 (Band 3). The M×N array may refer to M rows (e.g., one or more rows) and N columns (e.g., one or more columns) of antennas, where the number of rows, columns, and / or antennas in a row and column may include any number of antennas suitable for a particular application (e.g., communication via mmWave). Additionally, although the following description describes an antenna array 250 having a specific number of first frequency band antennas 251, second frequency band antennas 253, and third frequency band antennas 255, which represents a specific embodiment, the antenna array 250 may include any one or more of the first frequency band antennas 251, second frequency band antennas 253, and / or third frequency band antennas 255. The first frequency band antennas 251 may enable communication in a first frequency band or frequency range, the second frequency band antennas 253 may enable communication in a second frequency band or frequency range, and the third frequency band antennas 255 may enable communication in a third frequency band or frequency range. In some embodiments, the first frequency band, the second frequency band, and the third frequency band may include different frequency ranges. By way of example, the first frequency band may include low-band frequencies such as 700 MHz to 1.0 GHz, the second frequency band antennas 253 may enable communication in mid-band frequencies (such as 1.8 GHz to 2.2 GHz), and the third frequency band antennas 255 may enable communication in high-band frequencies (such as 20 GHz to 80 GHz).
[0046] Additionally, the transceiver 110 may be coupled to a power management module (PMM) 241 and an amplifier radio frequency integrated circuit (RFIC) 242 of the front glass panel 232. The power management module 241 may provide power to a power amplifier of the transceiver 110 to amplify the power of a transmit signal. The amplifier RFIC 242 may provide a mixing circuit to demodulate a radio frequency signal received by the transceiver 110 and modulate an intermediate frequency signal into a radio frequency signal for use in transmitting the transmit signal from the transceiver 110.
[0047] In some embodiments, the application processor 235 can control the antenna array selector 237 and / or the transceiver 110 (e.g., via the antenna array selector 237), and by extension, the antenna arrays 250 of the front glass panel 232, the back glass panel 234, the left side panel 236, and / or the right side panel 238. That is, the antenna array selector 237 can enable one or more of the antennas in one or more antenna arrays 250 (e.g., antenna arrays 250A, 250B, 250C, 250D) to transmit or receive wireless signals via the transceiver 110. In some embodiments, the antenna array selector 237 can enable the antennas of the right side panel 238 to transmit signals that contribute to a beamforming signal that is pointed right relative to the electronic device 100. By way of example, if Figure 1C If the electronic device 130 is positioned upward in the positive portion of the z-axis and facing the positive portion of the y-axis, the right side panel 238 can be positioned and transmit signals in the positive portion of the x-axis. The application processor 235 can also be communicatively coupled to the power management circuit 239 of each of the front glass panel 232, the main logic board 233, the back glass panel 234, the left side panel 236, and the right side panel 238 to control power-related functions for each of the panels.
[0048] The application processor 235 may include one or more microprocessors, one or more "general purpose" microprocessors, one or more special-purpose microprocessors, and / or one or more application-specific integrated circuits (ASICs), or some combination thereof. For example, the application processor 235 may include one or more reduced instruction set computing (RISC) processors. In some cases, the application processor 235 may perform processing (e.g., execute software programs and / or instructions) for specific functions, such as specific wireless communication-related functions. The specific functions may include receiving or generating wireless signals, selecting a specific antenna for transmitting or receiving signals using the antenna array selector 237, selecting an amplification level to amplify a transmit signal using the power management circuit 239, determining the gain of wireless signals transmitted and / or received from a specific transmitter and / or receiver associated with a specific antenna of the antenna array 250, and the like. In some cases, the application processor 235 may be integrated with the processor 102 and perform additional functions related to wireless communication, such as functions related to the display 108, adjusting bandwidth consumption, and the like.
[0049] In some embodiments, the application processor 235 may communicate with one or more memory devices ( Figure 2 Not shown) (such as Figure 1AThe memory device may communicate with the application processor 235 (e.g., memory 104) for processing instructions to perform functions related to wireless communication. The memory device may store information such as control software, configuration information, etc. In some embodiments, the application processor 235 and the memory device may be external to the main logic board 233 and / or the system package 230. The memory device may include tangible, non-transitory machine-readable media, such as volatile memory (e.g., random access memory (RAM)) and / or non-volatile memory (e.g., read-only memory (ROM)). The memory device may store a variety of information and may be used for a variety of purposes. For example, the memory device may store machine-readable and / or processor-executable instructions (e.g., in the form of software or a computer program) for execution by the application processor 235, such as instructions for enabling communication from a specific antenna that transmits or receives a signal that contributes to a beamformed signal transmitted or received at a specific frequency in a specific beam direction. The memory device may include one or more storage devices (e.g., non-volatile storage devices), which may include ROM, flash memory, a hard drive, or any other suitable optical, magnetic, or solid-state storage medium, or a combination thereof.
[0050] As shown, the system package 230 also includes a front glass panel 232, which may include one or more printed circuit boards coupled to a cover glass associated with the display 108. The front glass panel 232 may include a second antenna array 250B having M×N first frequency band antennas 251, M×N second frequency band antennas 253, and / or M×N third frequency band antennas 255. The antennas in the second antenna array 250B operate similarly to the antennas in the first antenna array 250A of the main logic board 233. That is, by way of example, the first frequency band antennas 251 may communicate wireless signals at low-band frequencies (e.g., 700 MHz to 1.0 GHz), the second frequency band antennas 253 may communicate wireless signals at mid-band frequencies (e.g., 1.8 GHz to 2.2 GHz), and the third frequency band antennas 255 may communicate wireless signals at high-band frequencies (e.g., 20 GHz to 80 GHz).
[0051] The front glass panel 232 may also include an amplifier RFIC 242 (e.g., a low noise amplifier (LNA) and a power amplifier (PA) radio frequency integrated circuit (RFIC)) and a power management module 241. The amplifier RFIC 242 may include circuitry between the antenna and the mixing circuitry that processes, for example, a signal at an incoming radio frequency (RF) before it is converted or demodulated to a lower intermediate frequency (IF) for processing (e.g., from RF to IF). By way of example, the amplifier RFIC 242 may include a processor 102 that processes instructions for functions performed by the amplifier RFIC 242 (e.g., instructions related to frequency conversion, transmitting a signal from a specific antenna with specific amplification, receiving a signal at a specific antenna, etc.) and / or a memory 104 that stores instructions related to the functions performed by the amplifier RFIC 242. In some embodiments, the amplifier RFIC 242 may include a bandpass filter that passes frequencies within a specific range and / or a bandstop filter that filters out frequencies from the specific range, a low noise amplifier that increases the signal strength of an incoming signal, a local oscillator that generates a radio frequency signal offset from the incoming signal to mix with the incoming signal, and / or a mixer that mixes the incoming signal with a signal from a local oscillator to convert the incoming signal to an intermediate frequency. The power converter (e.g., a direct current (DC) to DC converter (DC-DC converter)) of the power management module 241 can supply power to a power amplifier of the electronic device 100, for example, for amplifying a transmit signal. Therefore, dynamically changing the supply voltage from the power converter can correspondingly change the amount of amplification of the transmit signal from the power amplifier. In addition, the average power tracking (APT) of the power management module 241 can change the DC supply voltage based on the output power level to maintain the linearity of the power amplifier, while improving efficiency (e.g., reducing unnecessary power consumption of the power amplifier).
[0052] As illustrated, the system-in-package 200 also includes a left side panel 236, which may include one or more printed circuit boards connected to the left side of the electronic device 100. The left side panel 236 may also include a power management circuit 239, a transceiver 110, and a third antenna array 250C. Similarly, the system-in-package 200 includes a right side panel 238. The right side panel 238 may also include a power management circuit 239, a transceiver 110, and a fourth antenna array 250D. The power management circuit 239, transceiver 110, and antenna arrays 250C and 250D may operate and function similarly to the power management circuit 239, transceiver 110, and first antenna array 250A discussed with respect to the main logic board 233. As shown, the third antenna array 250C and the fourth antenna array 250D include M×N first frequency band antennas 251, second frequency band antennas 253, and third frequency band antennas 255. As previously mentioned, by way of example, the first band antenna 251 may communicate wireless signals at low-band frequencies, the second band antenna 253 may communicate wireless signals at mid-band frequencies, and the third band antenna 255 may communicate wireless signals at high-band frequencies.
[0053] As previously discussed, it can be difficult to integrate the antennas in antenna array 250, transceiver 110, and power management circuitry 239 within the same specific area within the package of the panel of system-in-package 200. Specifically, transceiver 110 and antenna array 250 can be co-located (e.g., near each other in the same or substantially the same area) within the package so that transceiver 110 can effectively control amplification, phase, gain, etc. of wireless signals while minimizing signal loss and noise that might otherwise result from a longer communication path (e.g., not co-located) between transceiver 110 and antenna array 250. Similarly, power management circuitry 239 can be co-located with transceiver 110 and antenna array 250 so that transceiver 110 can effectively control power-related functions of wireless signals from the antennas of antenna array 250 while also minimizing signal loss and noise. Furthermore, electronic device 100 can include additional antennas to achieve higher data throughput via the antennas and / or provide higher gain for wireless signals from the antennas. In some embodiments, the electronic device 100 includes additional components and / or additional antennas to accommodate carrier aggregation that is unique to a particular wireless carrier. The system in package 200 can efficiently accommodate co-located components, an additional number of antennas, other components, and / or packaging specifications while reducing the footprint (or maintaining the initial system package 200 size after the additional components and antennas are added). Although the following description describes space reduction packaging techniques applied to a particular panel of the system package 200, these techniques can also be applied to other panels of the system package 200. By way of example, the description of space reduction packaging techniques applied to the front glass panel 232 can also be applied to the main logic board 233, the back glass panel 234, the left side panel 236, and / or the right side panel 238. About Figures 3 to 6 Provides details on various space-reduction packaging technologies for integration of RF packages.

[0071] The pair of transceiver dies 530 and the corresponding pair of antenna arrays 524 can be rotated by a defined angle around the vertical axis (e.g., z-axis) of the RF package 550, for example, to improve the coverage of the transmitted / received wireless signals. By rotating the pair of antenna arrays 524 around the vertical axis of the RF package 550, the directionality and spatial coverage of the transmitted / received communication signals can be improved relative to the vertical axis of the RF package 550. Figure 5AThe RF package 500 is improved (for example, omnidirectionality can be achieved). When the mold 522 is included in the RF package 550, the corresponding pair of molds 522 can also rotate together with the pair of transceiver tube cores 530 and the corresponding pair of antenna arrays 524. The corresponding substrate 554 can be placed between each rotating structure (for example, the mold 522 and the transceiver tube core 530 and the antenna array 524) and the multilayer board 520.

Each assembly structure can then be mounted to a corresponding inner connector 556 and outer connector 558 of a specific length (e.g., height) such that the assembly structure can be tilted at a defined angle relative to the vertical axis of the RF package 550. Each rotating structure can be securely mounted to the inner connector 556 and outer connector 558 using a corresponding via connector 532. The substrate 554 can be an injection molded part that is shaped as needed and plated with, for example, conductive posts. In one embodiment, the substrate 554 is implemented as a three-dimensional printed plastic with metal inserts or connector-type components (e.g., inner connector 556 and outer connector 558). In another embodiment, the substrate 554 is implemented as a stamped plastic with laser direct imaging to define vias (e.g., via 532) and conductors (e.g., inner connector 556 and outer connector 558).
