CML Microcircuits’ CMX90A702 is a highly linear medium power amplifier operating in Frequency Range 2 (FR2) from 26.5 to 29.5 GHz that addresses the needs of 5G New Radio (NR) band n257 and n261. The CMX90A702 is a three-stage GaAs MMIC amplifier delivering +25 dBm (0.3 W) of output power at 1 dB gain compression, 21 dB of small signal gain and +32.5 dBm output third order intercept (OIP3). RF ports are matched to 50 Ω with an integrated DC blocking capacitor at the output.
The MPA is easy to monitor with an on-chip temperature-compensated RF power detector and fast-switching enabled circuit.
Additionally, the CMX90A702 uses an enhancement mode (E-mode) pHEMT process to ensure only positive supply voltages are required and makes single DC supply operation possible.
