SI4732 V6.8 Upgraded Version! Using FPC 0.2mm thin board, which reduces parasitic inductance to the ground compared to traditional fiber thick board PCB. The speaker is not installed on top. Features on-board IPEX interface, eliminating the need to solder the feeder. The top ground wire includes a welding hole on the right side of the fixed position, allowing for secure soldering with minimal effort, greatly reducing installation difficulty. A transient suppression diode is added to suppress transient voltage. The protection component has low parasitic capacitance, maintaining impedance matching during 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 old 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. High-quality high-frequency winding chip inductors are used, featuring high Q value, low internal resistance, and improved filtering selectivity. This product uses a non-glue substrate, offering better heat resistance and longer lifespan. The immersion gold manufacturing process is used, which is more costly than traditional tin-plated boards but provides higher reliability, stability, conductivity, and oxidation resistance. Components are machine-soldered, resulting in higher yield rates compared to manual soldering, with less thermal damage to the FPC soft board and components, significantly improving service life. Due to different production batches, there may be variations in product appearance, color, and printed text. These differences do not affect functionality.
