29-09-2016 | RFMW | Subs & Systems

Integrating a high linearity SPDT RF switch with a low-noise amplifier (LNA) having bypass capability, the Qorvo RFFM4554 5G front-end module (FEM) is now available from RFMW. The LNA receive gain is 13.5dB with noise figure rated at a notably low, 1.7dB. With frequency coverage from 4.9 to 5.925GHz, the RFFM4554 supports 5G WiFi CPEs, gateways and set top boxes. It also finds homes in WiFi access points, routers and IoT (internet of things) products operating in this ISM band. An internal 2.4GHz rejection filter offers 35dB of attenuation and external filtering can be added to reduce 2.4GHz interference. Operating voltage is 3 to 5.5V and the RFFM4554 comes in a small, 2.3mm x 2.3mm DFN package.
