The ARQSF3753-RX-A from iCana is a dual-channel, receiver front-end module (FEM) designed for 3GPP 5G NR FR1 bands n77 and n79 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 1.45 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 compact pin-to-pin compatible FEM product line designed for wireless infrastructure supporting major 3GPP bands. Pin-to-pin compatibility exists within product sub-groups ‘A’ and ‘B’.
