CMX90A702 28 GHz 5G Medium Power Amplifier

CML Micro’s CMX90A702 highly linear medium power amplifier (MPA) operates in the Frequency Range 2 (FR2) from 26.5 GHz to 29.5 GHz, addressing the needs of 5G New Radio (NR) band n257 and n261. The CMX90A702 is a three-stage gallium arsenide (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 and control with an on-chip temperature-compensated RF power detector and fast-switching enable circuit. An enhancement mode (E-mode) pHEMT process ensures only positive supply voltages are required, making single DC supply operation possible.
