Both of DRF7020D20 and DRF4432D20 are 20dBm transceiver modules. DRF4432D20 is designed on the base of SI4432. Comparing to DRF7020D20, it has more compact size and higher data rate. It also contains RSSI indication function which is very useful for applications with signal strength measuring requirement such as wireless sensor network, AMR network, etc. The working voltage of DRF4432D20 can be minimized to 2.2~3.3V but the output power will be affected with the decreasing of power supply

DRF7020D20 is one of most mature modules based on ADF7020 RFIC. It also adopts high efficient EDAC technology which makes communication link more robust. DRF7020D13, DRF7020D20 and DRF7020D27 modules use the same chip and data format so they can communicate with default settings. The different output powers of DRF7020Dxx series modules provide flexibility in communication range and BOM cost.
