There is a 125-VFBGA package on the board that RF transceiver IC is used to save space. In order to mount the RF transceiver's mounting, Surface Mount is used.In this case, the result is a TxRx + MCU with transceiver RF's high efficiency.High reliability is achieved by using advanced transceiver RF' packagings Tape & Reel (TR).The RF transceiver that you are looking at comes from our well-known Flex Gecko series product line.The frequency of 169MHz 315MHz 433MHz 490MHz 868MHz 915MHz determines how RF transceiver operates .
