Description

Technical Field

[0001] This utility model relates to the field of mobile phone technology, and more specifically, to a 4G communication miniature mobile phone. Background Technology

[0002] Against the backdrop of rapid iteration in mobile communication technology, the feature phone market is showing a trend of polarization: on the one hand, smartphones continue to develop towards larger screens and higher performance; on the other hand, the demand for ultra-small portable communication devices is becoming increasingly prominent among certain user groups, especially in scenarios such as the elderly, child monitoring, outdoor emergencies, and backup phones, where miniaturized feature phones have irreplaceable advantages. However, existing 4G feature phones face multiple technical bottlenecks in achieving miniaturization, making it difficult to achieve an ideal balance between portability and functionality.

[0003] Traditional 4G feature phones generally adopt a modular design architecture, with core components such as baseband chips, RF front-ends, antenna modules, and batteries laid out separately, resulting in redundant PCB board area. For example, 4G communication modules need to support multiple frequency bands (such as LTE-FDDB1 / B3 / B5 / B8), and their RF circuitry is far more complex than that of 2G / 3G devices, with discrete power amplifiers (PAs) and filters occupying a large amount of space. At the same time, traditional spring-loaded antennas or PCB antennas are inefficient in design, often requiring a clearance of more than 10mm to meet signal strength requirements, directly restricting the reduction of the overall device size.

[0004] With the popularization of IoT technology, ultra-small communication terminals are experiencing explosive demand in emerging fields such as wearable devices, emergency rescue equipment, and concealed monitoring devices. However, due to the aforementioned technological limitations, existing ultra-small communication terminals cannot break through the physical boundary of 65mm×35mm×18mm, which severely restricts the expansion of application scenarios.

[0031] In this embodiment, the SR3595D single-chip radio transceiver has 6 single-ended transmit ports, 12 main ports, and 11 diversity single-ended receive ports, which has the following advantages:

[0032] 1. Frequency band compatibility: Supports mainstream global cellular communication frequency bands, covering 2G, 3G and 4G systems, and is suitable for diverse network deployment scenarios.

[0034] 3. Multiple transmit ports: Provides 6 single-ended transmit ports, each output driver stage is matched to a 50Ω system impedance to ensure efficient and stable signal transmission.

[0035] Specifically, the SR3595D single-chip radio transceiver's linear transceiver architecture is used in 2.5G, 3G, and 4G systems, providing excellent performance and design margins exceeding 3GPP requirements. Secondly, the SR3595D single-chip radio transceiver's direct modulation transmitter, employing direct modulation technology, simplifies transmit link design. The performance of the 2.5G receive and transmit links meets out-of-band noise specifications without the need for additional RF filters, reducing cost and complexity and enabling miniaturization of 4G mobile phones.

[0036] The 4G communication miniature mobile phone provided in this embodiment of the utility model adopts the SR3595D single-chip radio transceiver, which achieves the lowest power consumption while maintaining high performance, meets the requirements of mobile devices for battery life, and can also significantly reduce the number of components and shrink the overall size of the 4G communication mobile phone, thus enabling the miniaturization of the 4G communication mobile phone.

[0037] In this embodiment, the power amplifier module is a multimode multiband (MMMB) power amplifier with model number FX5627Y.

[0038] The FX5627Y multimode multiband (MMMB) power amplifier supports mainstream communication standards such as CDMA, WCDMA, TD-SCDMA, TDD-LTE and FDD-LTE. The FX5627Y multimode multiband (MMMB) power amplifier module achieves flexible RF control through the MIPI RFFE (RF front end) interface, and adopts a three-band amplifier architecture and multi-band switching output.

[0039] Specifically, the FX5627Y multimode multiband (MMMB) power amplifier module supports full programmability through the industry-standard MIPI RF front-end control interface, allowing dynamic configuration of amplifier paths, switching states, and power output to adapt to different communication modes and frequency band switching.

[0040] The 4G communication miniature mobile phone provided in this embodiment adopts the FX5627Y multimode multiband (MMMB) power amplifier module. Since the FX5627Y multimode multiband (MMMB) power amplifier module has a three-band programmable architecture, MIPIRFFE interface control and multimode multiband compatibility, it provides a high-efficiency, flexible and compact radio frequency front-end for the 4G communication miniature mobile phone. It not only meets the communication needs of the 4G communication miniature mobile phone, but also enables the 4G communication miniature mobile phone to be miniaturized.

[0041] In this embodiment, the front-end module is a transmit / receive front-end module with model number FX5596Y.

[0042] The FX5596Y transmit / receive front-end module (FEM) supports Class 12 GPRS, EDGE multi-slot operation, and TD-SCDMA / TDD-LTE linear transmission, making it suitable for 4G networks. Furthermore, the FX5596Y FEM provides 14 transmit / receive (TRx) ports and enables broadband 3G / 4G RF switching through an integrated directional coupler, simplifying the connection between the antenna and the RF front-end.

[0043] Specifically, the FX5596Y transmit / receive front-end module (FEM) consists of the following key subsystems, which together achieve efficient processing of multi-band RF signals. The FX5596Y transmit / receive front-end module (FEM) consists of a CMOS controller, a low-frequency PA block supporting the GSM850 / 900 band, a high-frequency PA block supporting DCS1800 / PCS1900, TD-SCDMA bands 34 / 39 and TDD-LTE bands 34 / 39, an input / output matching network, a Tx harmonic filter, an RF switch, and a directional coupler with an antenna output.

[0044] The CMOS controller internally incorporates a low-current power amplifier (PA) controller. As a submodule of the CMOS controller, the low-current PA controller is used for power management, bias configuration, and timing control. By integrating a MIPI interface and decoding circuitry, the PA controller achieves intelligent management of the PA. The low-current PA controller integrates a MIPI RFFE interface and decoder circuitry. In GMSK mode, it uses the VRAMP voltage to control the envelope amplitude, effectively reducing the sensitivity of the PA output to input drive signal fluctuations, temperature changes, power supply fluctuations, and process differences. Simultaneously, it ensures precise timing coordination between MIPI commands and VRAMP signals, achieving high isolation between the antenna path and the transmitter VCO, and completing VCO pre-tuning before the transmission burst. In EDGE and TD-SCDMA / TDD-LTE linear modes, the low-current PA controller combines VRAMP voltage adjustment with dynamic bias parameters configured by MIPI to further optimize the PA's linear characteristics and energy efficiency balance, meeting the signal quality and power efficiency requirements of multi-standard communication scenarios.

[0045] In this embodiment, the baseband processing unit integrates a Bluetooth 5.0+EDR module and an FM module.

[0046] The overall structural dimensions of the 4G communication miniature mobile phone provided in this embodiment can be miniaturized, mainly through the following methods:

[0047] 1. The baseband chip integrates a Bluetooth 5.0+EDR module and an FM module, reducing the space occupied by separately configured Bluetooth 5.0+EDR modules and FM chips;
