SI4732 V6.8 FPC module + 512 KB chip + loop antenna for K5 K6 HF Description

SI4732 V6.8 FPC Module + 512 KB Chip + Loop Antenna for K5 K6 HF Description SI4732 V6.8 Improved Version!!! By using a 0.2 mm thin FPC board, the parasitic inductance to ground is reduced compared to conventional fiberglass boards. The speaker is not mounted on the top side. Thanks to the integrated IPEX interface, the board does not need to be soldered to the lead. The top ground wire also has a weld hole on the right side of the fixed position. With light pressure, the solder joint can be firmly soldered, which significantly simplifies installation and assembly. An additional surge protection diode suppresses overvoltages, and the parasitic capacitance of the protection component itself adjusts the impedance during the original signal transmission, thus preventing signal distortion. The internal amplifier IC uses components with a maximum signal gain of 19 dB. An external active antenna, as required in the previous version, is not necessary. A standard telescopic antenna is sufficient for good reception. (Not included in the package)
Add an audio amplifier circuit to solve the low volume problem of the SSB single-sideband in the English CEC firmware.
FM (frequency modulation) and RF (amplitude modulation medium and shortwave) bandpass filters are added to the adapter board, providing stronger interference suppression.
High-quality RF winding chip inductors feature high Q, low internal resistance, and stronger filter selectivity.
The softboard FPC uses a non-adhesive substrate, and PI is available in two types: adhesive substrate and non-adhesive substrate. This product uses a non-adhesive substrate that is more heat-resistant and durable. The immersion gold plating process is more expensive than conventional tin-plated boards, but it offers higher reliability and stability in terms of conductivity and oxidation resistance. The components are machine-soldered, allowing for a higher yield than conventional manual soldering and causing less thermal damage to the FPC softboard and components, thus significantly improving service life. Due to batch variations, there may be differences in appearance, color, and printing, but these do not affect usability. Color: Orange and yellow. Material: FPC. Package contents: 1 x SI4732 V6.8 FPC module with accessory kit. 1 x BL24CM2A 512 KB chip (factory serial number varies by batch). 1 x loop antenna (printing varies by batch). Only the above items are included; other products are not included.
Note: Light reflections and different displays may cause the color of the item in the picture to be slightly different from the actual color. The allowable measurement error is +/- 1-3 cm.
