Power amplifier CMX90A702

RFswitchinglinear

The CMX90A702 is a highly linear Medium Power Amplifier operating in Frequency Range 2 (FR2) from 26.5 to 29.5 GHz, addressing the needs of 5G New Radio (NR) band n257 and n261. 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 ? 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. Using an enhancement mode (E-mode) pHEMT process ensures only positive supply voltages are required, thus making single DC supply operation possible.
