High-performance RF front-end module for 5G mobile terminals

The WEA2630FE45G is a high-performance RF front-end module designed for 5G mobile terminals. The front-end combines a low noise high linearity LNA, a low insertion-loss, highisolation TR switch, a high-efficiency PA, a Power Detector and a Temperature Sensor with ADCs and a SPI. The WEA2630FE45G is powered from a single 3.6V supply and the biasing is generated with an on-chip bandgap reference voltage. The receive path (LNA+SW) is designed to provide 18dB of gain and a noise figure less than 4dB. The transmit path (PA+SW) provides saturated output power of 18dBm. The WEA2630FE45G is fabricated on GlobalFoundries 45RFSOI process occupying a total silicon area of 1.5mm2.
