CML MICROCIRCUITS CMX90A702 28 GHz 5G Medium Power Amplifier, (MPA) was developed using firm’s SµRF RFIC/MMIC design capability, and targets 5G mmWave infrastructure applications, including repeaters, small cells, customer-premises equipment (CPE), passive antenna arrays and 5G backhaul applications. Operating in Frequency Range 2 (FR2) from 26.5 to 29.5 GHz, the highly linear device supports 5G New Radio (NR) bands n257 and n261, with a 400 MHz 64-QAM carrier signal achieving EVM of less than 4 % at 18 dBm mean power. Device delivers +25 dBm (0.3 W) of output power at the 1dB gain compression point with Power Added Efficiency of 26 % to ensure leading class power efficiency.
