DRA818U is a type of compact wireless voice transceiver module based on RFIC RDA1846 and works in UHF band. It integrates high speed microcontroller, high performance wireless transceiver IC, high power PA, audio process and squelching circuits. It provides standard UART interface which users can easily configure appropriate parameters for different applications. Users can easily construct a walkie-talkie system by connecting microphone, audio PA and speaker.

DRF4463F is a type of low cost RF front-end transceiver module based on SI4463 from Silicon labs. It keeps all the advantages of RFIC SI4463 but simplifies the circuit design. The high sensitivity (-126dBm) and 20dBm high power output make the module suitable for most short range applications.

DRF4431F13 is a type of low cost RF front-end transceiver module based on SI4431 from Silicon labs. It keeps all the advantages of RFIC SI4431 but simplifies the circuit design. The high sensitivity (-121dBm) and 13dBm output power make the module suitable for most short range applications.

DRF4432F20 is a type of low cost RF front-end transceiver module based on SI4432 from Silicon labs. It keeps all the advantages of RFIC SI4432 but simplifies the circuit design. The high sensitivity (-121dBm) and 20dBm output power make the module suitable for most short range applications.

DRF4431F27-086S is a type of 868Mhz 500mW high power RF front-end transceiver module based on SI4431 from Silicon labs. LNA and PA are added in order to achieve the longest distance.
