Generic Walkie-Talkie SI4732 FPC Board Module for Quansheng UV-K5/K6,Chip Crystal Oscillator Component for HF Shortwave and Full-Band Reception,Support Single Antenna and Dual Antenna

• 👍👍【Audio output amplification】By integrating an audio amplifier, the problem of too low volume in SSB single-sideband transmission is effectively solved, greatly improving the sound quality. 👍👍【Advanced component selection】Use 0.12mm thick FPC soft board to ensure safety and reliability, prevent short circuit, and support high-quality high-frequency winding chip inductors with enhanced filtering capabilities. 👍👍【Redesigned bandpass filter】Redesigned FM and HF bandpass filters to optimize performance and ensure better signal clarity and reception in different frequency bands. 👍👍【Enhanced protection function】Added ESD tube at the input end to provide static electricity and signal protection during dual-antenna UV transmission, protecting the system from potential damage. 👍👍【Dual antenna optimization】Adding bandpass filtering at the antenna input end, combined with the use of feeder and SMA connector, can achieve separate HF antenna connection without affecting the UV performance of the original machine.
