[0001] Cross-references to related applications
[0002] This application claims priority to U.S. Patent Application No. 18 / 092,683, filed January 3, 2023, the entire contents of which are incorporated herein by reference. Technical Field
[0003] This disclosure relates to packaging technologies, and more specifically to the integration of radio frequency front-ends for size reduction and performance improvement. Background Technology
[0004] Generally, radio frequency (RF) devices may include packages such as system-in-package (SIP). A SIP combines a substrate, die, multiple integrated circuits, and / or passive devices into a single package. A SIP may be made of semiconductor materials such as silicon. For example, the substrate and die may include silicon on which integrated circuits are fabricated. The substrate, die, and devices may be coupled by leads bonded to the package or by solder joints (e.g., solder balls or pads). By way of example, dies may be stacked (e.g., 2.5D or 3D stacked structures) to combine dies into the same package instead of placing them on a printed circuit board. In some cases, a SIP may also include multiple packages that are stacked (e.g., using stacked packaging technology) or have dies embedded in a substrate.
[0005] For example, radio frequency (RF) devices supporting communication over millimeter-wave (mmWave) frequencies typically provide support at frequencies of 30 GHz or close to 30 GHz. In some cases, RF devices may also support mmWave communication via additional mmWave bands for a wider frequency coverage range (such as 30 GHz–300 GHz). Multiple antennas (e.g., antenna arrays) of the RF device can transmit signals that are combined to form a beam (e.g., beamforming signal) for communication over mmWave. To achieve consistent coverage (e.g., from base stations associated with mmWave communication), the RF device may include multiple antenna arrays located in different parts of the RF device. However, assembling these multiple antenna arrays in a system-in-package (SIIP) of the RF device can consume space and undesirably increase the size of the RF device. Summary of the Invention

[0040] Figure 2 yes Figure 1A A schematic diagram of a system 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 three-dimensional (3D) stacks of printed circuit boards. That is, one or more panels may be positioned on top of or below one or more other panels. Furthermore, at least one panel may include a redistribution printed circuit board that provides connectivity between panels coupled to the redistribution printed circuit board.
[0041] In the depicted embodiments, system package 200 includes packages for a front glass panel 232 (e.g., a front surface panel or cover glass panel), a main logic board 233 having a rear glass panel 234, a left side panel 236, and a right side panel 238. Although the following description depicts panels 232, 234, 236, and 238 as being disposed on the front, rear, left, and right sides of electronic device 100, respectively, representing a particular embodiment, system package 200 described herein may additionally or alternatively include panels disposed in other areas of electronic device 100 that may include one or more antennas. For example, system package 200 may also include a top side panel or a bottom side panel, respectively disposed on the top or bottom of electronic device 100, adjacent to left side panel 236 and right side panel 238. Furthermore, although the following description describes an antenna array, representing a particular embodiment, system 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, power management circuitry 239, transceiver 110, antenna array selector 237, application processor 235, and a first antenna array 250A. The application processor 235 may be coupled to the power management circuitry 239 to control power functions, including power functions related to wireless communication. The power management circuitry 239 may include one or more integrated circuits and controls the power supplied to the main logic board 233 and / or components of the electronic device 100 (including, for example, transceiver 110 and / or antenna array selector 237) (e.g., via processor 102). By way of example, the power management circuitry 239 may control the following processes: supplying power to the main logic board 233; supplying power to components, panels 232, 234, 236, and / or 238 on or coupled to the main logic board 233; 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 in the figure, transceiver 110 is coupled to antenna array selector 237, first antenna array 250A of rear glass panel 234, and components of front glass panel 232. Antenna array 250A includes multiple antennas that transmit and / or receive wireless signals, and can form a directional beam using signals transmitted by each antenna. As previously mentioned... Figure 1AThe transceiver 110 discussed herein is a device that includes a transmitter and a receiver in a single package and can transmit and receive data via wireless signals transmitted on a specific radio frequency using an antenna in a first antenna array 250A. Specifically, transceiver 110 may include a transmitter and a receiver that include components facilitating the transmission and reception of wireless signals, such as those used for transmission and reception between electronic devices 100 using mmWave communication technology or any other suitable communication protocol. When communicating on mmWave frequencies, electronic devices 100 may utilize beamforming techniques to form directional beams, as previously mentioned. The transmitter of transceiver 110 may include one or more phase shifters, a transmitter power detector, and a power amplifier. The transmitter phase shifter may modulate (e.g., phase-shift) the transmitted signal (e.g., a wireless signal transmitted from an antenna in the first antenna array 250A) and may form a beam that can be manipulated in a particular 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 may amplify the power level of the transmitted signal. Specifically, a power amplifier supply voltage can be supplied to the power amplifier to control the amplification provided by the power amplifier (e.g., increasing or decreasing the amplification, which can affect the antenna gain at the corresponding antenna). The transmitter power detector can measure the power of the transmitted signal transmitted from the antenna in the first antenna array 250A.
[0044] The receiver of transceiver 110 may include one or more receiver phase shifters, low-noise amplifiers, and receiver power detectors. The receiver phase shifters and receiver power detectors may operate similarly to those of transmitter phase shifters and transmitter power detectors. The low-noise amplifier may amplify the power level of the 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] An antenna array selector 237, which can be coupled to transceiver 110, can activate or enable communication from one or more antennas in antenna array 250 (such as first antenna array 250A). For example, antenna array selector 237 can selectively enable multiple antennas to adapt to data throughput. As shown, first antenna array 250A is disposed at rear glass panel 234. Rear glass panel 234 may include one or more printed circuit boards coupled to the rear surface (e.g., rear glass) of electronic device 100. As shown, first antenna array 250A may include an M×N array of first band antenna 251 (band 1), second band antenna 253 (band 2), and third band antenna 255 (band 3). 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, wherein the number of antennas in rows, columns, and / or rows and columns may include any number of antennas suitable for a particular application (e.g., communication via mmWave). Additionally, although the following description depicts an antenna array 250 having a specific number of first band antennas 251, second band antennas 253, and third band antennas 255, representing a particular embodiment, the antenna array 250 may include any one or more of the first band antennas 251, second band antennas 253, and / or third band antennas 255. The first band antenna 251 enables communication in a first band or frequency range, the second band antenna 253 enables communication in a second band or frequency range, and the third band antenna 255 enables communication in a third band or frequency range. In some embodiments, the first, second, and third bands may include different frequency ranges. By way of example, the first band may include low-frequency band frequencies such as 700 MHz to 1.0 GHz, the second band antenna 253 may enable communication in mid-frequency band frequencies (such as 1.8 GHz to 2.2 GHz), and the third band antenna 255 may enable communication in high-frequency band frequencies (such as 20 GHz to 80 GHz).
[0046] Additionally, transceiver 110 may be coupled to a power management module (PMM) 241 and an amplifier radio frequency integrated circuit (RFIC) 242 on the front glass panel 232. The power management module 241 provides power to the power amplifier of transceiver 110 to amplify the power of the transmitted signal. The amplifier RFIC 242 provides mixer circuitry to demodulate the radio frequency signal received by transceiver 110 and modulate the intermediate frequency signal into a radio frequency signal for transmission from transceiver 110.
[0047] In some embodiments, application processor 235 may control antenna array selector 237 and / or transceiver 110 (e.g., via antenna array selector 237), and by extension, control antenna arrays 250 of front glass panel 232, rear glass panel 234, left side panel 236, and / or right side panel 238. That is, antenna array selector 237 may enable one or more antennas in one or more antenna arrays 250 (e.g., antenna arrays 250A, 250B, 250C, 250D) to transmit or receive wireless signals via transceiver 110. In some embodiments, antenna array selector 237 may enable the antenna of right side panel 238 to transmit signals that contribute to beamforming signals directed to the right relative to electronic device 100. For example, if Figure 1C If the electronic device 130 is positioned upwards in the positive portion of the z-axis and facing the positive portion of the y-axis, then the right panel 238 can be positioned and transmit signals in the positive portion of the x-axis. The application processor 235 is also communicatively coupled to the power management circuitry 239 of each of the front glass panel 232, main logic board 233, rear glass panel 234, left panel 236, and right panel 238 to control power-related functions for each panel.
[0048] 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, application processor 235 may include one or more Reduced Instruction Set Computing (RISC) processors. In some cases, application processor 235 may perform processing for specific functions, such as specific wireless communication-related functions (e.g., executing software programs and / or instructions). Specific functions may include receiving or generating wireless signals, using antenna array selector 237 to select a specific antenna for transmitting or receiving signals, using power management circuitry 239 to select amplification levels to amplify transmitted signals, determining the gain of wireless signals transmitted and / or received from a specific transmitter and / or receiver associated with a specific antenna of antenna array 250, etc. In some cases, application processor 235 may be integrated with processor 102 and perform additional functions related to wireless communication, such as functions related to display 108, adjusting bandwidth consumption, etc.
[0049] In some implementations, the application processor 235 may be connected to one or more memory devices ( Figure 2 (not shown in the image) (such as...) Figure 1AThe memory device 104 communicates with the application processor 235 to process instructions for performing 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 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 can store a variety of information and can 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 computer programs) for execution by the application processor 235, such as instructions for implementing communication from a specific antenna that transmits or receives signals contributing to beamforming signals 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) that may include ROM, flash memory, hard disk drives, or any other suitable optical, magnetic, or solid-state storage media or combinations thereof.
[0050] As shown in the figure, 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-band antennas 251, M×N second-band antennas 253, and / or M×N third-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-band antennas 251 may transmit wireless signals at low-frequency bands (e.g., 700 MHz to 1.0 GHz), the second-band antennas 253 may transmit wireless signals at mid-frequency bands (e.g., 1.8 GHz to 2.2 GHz), and the third-band antennas 255 may transmit wireless signals at high-frequency bands (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 an antenna and a mixer circuitry that processes the signal, for example, 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 particular antenna with a particular amplification, receiving a signal at a particular antenna, etc.) and / or a memory 104 that stores instructions related to the functions performed by the amplifier RFIC 242. In some implementations, amplifier RFIC 242 may include a bandpass filter that allows frequencies within a specific range to pass through and / or a bandstop filter that filters out frequencies from that specific range, a low-noise amplifier that increases the signal strength of the incoming signal, a local oscillator that generates an RF 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 the local oscillator to convert the incoming signal to an intermediate frequency. The power converter (e.g., a DC-DC converter) of power management module 241 may supply power to the power amplifier of electronic device 100, for example, for amplifying the transmitted signal. Therefore, dynamically changing the supply voltage from the power converter can correspondingly change the amplification of the transmitted signal from the power amplifier. Furthermore, the average power tracking (APT) of power management module 241 may vary 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, system package 200 also includes a left side panel 236, which may include one or more printed circuit boards connected to the left side of electronic device 100. Left side panel 236 may also include power management circuitry 239, transceiver 110, and a third antenna array 250C. Similarly, system package 200 includes a right side panel 238. Right side panel 238 may also include power management circuitry 239, transceiver 110, and a fourth antenna array 250D. Power management circuitry 239, transceiver 110, and antenna arrays 250C, 250D may operate and function similarly to power management circuitry 239, transceiver 110, and first antenna array 250A as discussed with respect to main logic board 233. As shown, the third antenna array 250C and fourth antenna array 250D include M×N first-band antennas 251, second-band antennas 253, and third-band antennas 255. As previously mentioned, by way of example, the first band antenna 251 can transmit wireless signals at low frequency bands, the second band antenna 253 can transmit wireless signals at mid frequency bands, and the third band antenna 255 can transmit wireless signals at high frequency bands.
[0053] As previously discussed, integrating the antenna, transceiver 110, and power management circuitry 239 of antenna array 250 into the same specific area within the panel package of system package 200 can be challenging. Specifically, transceiver 110 and antenna array 250 may be co-located (e.g., close to each other in the same or substantially the same area) within the package, allowing transceiver 110 to effectively control the amplification, phase, gain, etc., of the wireless signal 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 may be co-located with transceiver 110 and antenna array 250, allowing transceiver 110 to effectively control the power-related functions of the wireless signal from the antenna of antenna array 250 while also minimizing signal loss and noise. Furthermore, electronics 100 may include additional antennas to achieve higher data throughput via the antenna and / or provide higher gain of the wireless signal from the antenna. In some implementations, electronic device 100 includes additional components and / or additional antennas to accommodate carrier aggregation specific to a particular wireless carrier. System package 200 can effectively accommodate co-located components, additional antennas, other components, and / or package specifications while reducing footprint (or maintaining the initial system package 200 size after adding additional components and antennas). Although the following description describes space-saving packaging techniques applied to specific panels of system package 200, these techniques can also be applied to other panels of system package 200. By way of example, the description of space-saving packaging techniques applied to front glass panel 232 can also be applied to main logic board 233, rear glass panel 234, left side panel 236, and / or right side panel 238. About Figures 3 to 6 Provides details on various space-saving packaging technologies for integration in RF packaging.

[0071] A pair of transceiver dies 530 and a corresponding pair of antenna arrays 524 can be rotated by a defined angle about the vertical axis (e.g., the 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 about 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 (e.g., omnidirectionality is enabled). When the die 522 is included in the RF package 550, a corresponding pair of dies 522 can also rotate together with a pair of transceiver dies 530 and a corresponding pair of antenna arrays 524. A corresponding substrate 554 can be placed between each rotating structure (e.g., the die 522 with the transceiver die 530 and the antenna array 524) and the multilayer board 520. Furthermore, the corresponding rotating antenna array 524 can be coupled to the front-end package 502 using a via connector 532, which is connected to the multilayer board 520 using a corresponding inner connector 556 and a corresponding outer connector 558.

Each rotating structure including the die 522, the transceiver die 530, and the antenna array 524 can be assembled first. Subsequently, each assembly structure can be mounted onto 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 through-hole connector 532. The substrate 554 can be an injection-molded part formed as needed and plated with, for example, conductive pillars. In one embodiment, the substrate 554 is realized as a three-dimensional printed plastic having metal inserts or connector-type components (e.g., inner connector 556 and outer connector 558). In another embodiment, the substrate 554 is realized as a stamped plastic using laser direct imaging to define vias (e.g., via 532) and conductors (e.g., inner connector 556 and outer connector 558).

Each available space 634 can be used to integrate one or more additional components into RF package 600, for example, to provide improved performance.
[0074] A multilayer board 620 may be placed between a front-end package 602 and some antenna arrays 624. An insulating film substrate 616 may be connected to the multilayer board 620 using a connector 618. The connector 618 may be, for example, a solder ball connector, a microbump, some other type of connector, or some combination thereof. The respective antenna arrays 624 may be connected to the multilayer board 620 using a via connector 632. The via connector 632 may carry signals between the transceiver die 630 / antenna array 624 and one or more components of the front-end package 602. The via connector 632 may be, for example, a plated via, a copper-filled via, some other type of via, or some combination thereof. The multilayer board 620 may be replaced by a flexible board 620. Alternatively, the multilayer board 620 may be replaced by a board 620 having at least one embedded component. The RF package 600 may also include a die 622 (e.g., an antenna substrate), and each die 622 may be placed on a respective antenna array 624. Each transceiver die 630 and each passive component 628 can be integrated into a corresponding die 622. When the die 622 is included in the RF package 600, a multilayer board 620 can be placed between the front-end package 602 and some dies 622.
[0075] The RF package 600 may also include an adhesive 640 (e.g., a flexible adhesive or a rigid-flex adhesive) coupled to the multilayer board 620 using a pair of connectors 638. The connectors 638 may be, for example, solder ball connectors, microbumps, some other type of connector, or some combination thereof. Instead of being located at the top surface and / or bottom surface of the multilayer board 620, at least one connector 638 may be positioned between the adhesive 640 and a side surface of the multilayer board 620. At least one antenna array 642 and at least one transceiver die 648 (which may optionally be integrated into the die 636 along with passive components 646) may be connected to the multilayer board 620 using a via connector 650 connected to the adhesive 640. The via connector 650, together with the connectors 638, may carry signals between the transceiver die 648 / antenna array 642 and one or more components of the front-end package 602. The via connector 650 may be, for example, plated vias, copper-filled vias, some other type of via, or some combination thereof. Each structure, including mold 636, transceiver die 648, and antenna array 642, can be assembled first. Then, each assembled structure can be attached to adhesive 640, which is then attached to a pair of connectors 638. In this way, the wireless communication performance of the RF package 600 can be improved as wireless signals are transmitted / received in more directions.
