SI4732 V6.8 Upgraded version! Using FPC 0.2mm thin board, compared with traditional fiber thick board PCB, it reduces parasitic inductance to ground. The speaker is not installed on top. Features on-board IPEX interface, eliminating the need to solder feeder cables. The top ground wire includes a welding hole on the right side of the fixed position, allowing for secure soldering with minimal effort, significantly reducing installation difficulty. A transient suppression diode is added to suppress transient voltage. The protection component has low parasitic capacitance, maintaining impedance matching during original signal transmission and preventing signal distortion. The internal amplifier circuit IC uses components with a maximum signal gain of 19dB. No external active antenna is required, unlike the older version. An ordinary pull-rod antenna is sufficient for good reception performance. (Antenna not included) Includes an audio amplifier circuit to address low volume issues with SSB single-sideband in CEC English firmware. FM (frequency modulation) and HF (amplitude modulation medium and short wave) bandpass filters are integrated into the adapter board, providing enhanced anti-interference capability. Equipped with high-quality high-frequency wound chip inductors featuring high Q value, low internal resistance, and improved filtering selectivity. This product uses a non-glue substrate, offering better heat resistance and extended lifespan. The immersion gold plating process is used, which is more costly than traditional tin plating but provides higher conductivity reliability and superior oxidation resistance. Components are machine-soldered, resulting in higher yield rates compared to manual soldering, with reduced thermal damage to the FPC soft board and components, greatly improving service life.
