Description

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 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.

Using an enhancement mode (E-mode) pHEMT

process ensures only positive supply voltages are

required, thus making single DC supply operation

possible.
