UMS CHC6054-QQA RF front-end module

The CHC6054-QQA, from United Monolithic Semiconductors (UMS), is a high-power front-end module incorporating transmit and receive paths and a transmit/receive switch. It operates in the 24.25 to 30.5 GHz frequency range and is designed for telecom radio systems applications.

The RF front-end module typically exhibits an Rx gain of 18 dB with a low noise figure of 3.2 dB, and a Tx gain of 28 dB with +31 dBm saturated output power. It features high linearity with an ACPR of -36 dBc at +23 dBm average Pout.

Additional features include: Tx output Psat of +31 dBm (@ 5 dB gain comp); Rx input P1 dB of -7 dBm; and up to 1024 QAM with EVM <3.5% at CS 56 or 112 MHz.

It is manufactured on 150 nm gallium nitride on silicon carbide (AlGaN/GaN on SiC) and 150 nm gallium arsenide and provided in a plastic QFN package measuring 4 x 5 mm.
