ARQSF2442-RX-A is a dual-channel, front-end module (FEM) designed for 3GPP 5G NR FR1 bands n7, n38, n41, n48, n53, n77, and n78 Wireless Infrastructure. Each channel consists of a silicon SPDT switch and a two-stage GaAs LNA with bypass. The LNA provides high and low gain modes with 1.3 dB noise figure. The SPDT supports high power input signals up to 12 W average power with 10 dB PAR.
This FEM is part of arQana’s FEM product line designed for wireless infrastructure supporting major 3GPP bands.
