RF Micro Devices has expanded its Wi-Fi product portfolio to include three new front end modules (FEMs): the RF5325, RF5345 and RF5725.
Each device contains a 2,4 GHz power amplifier (PA) designed to optimise linearity while minimising current consumption. Each FEM integrates an output power coupler, transmit (Tx) low pass filtering and a single-pole three-throw (SP3T) switch capable of switching between Wi-Fi receive (Rx), Wi-Fi transmit (Tx) and Bluetooth Rx/Tx operations.
The integrated coupler lowers bill-of-material costs and reduces the board area necessary for front end implementation in chipsets utilising closed loop power control to adjust output power. The RF5345 and RF5725 also integrate a low noise amplifier (LNA) for RF architectures requiring additional Rx gain. All devices are available in 3 x 3 x 0,5 mm packages and feature 3,3% error vector magnitude (EVM).
