CMX90A702屬于RF/IF射頻/中頻RFID的射頻放大器。由CML Microcircuits制造生產(chǎn)的CMX90A702射頻放大器在射頻應(yīng)用中，射頻放大器產(chǎn)品可用于信號增益和緩沖。這些產(chǎn)品與通用運(yùn)算放大器的不同之處在于，它們通常適用于更高的頻率，更傾向于提供不可調(diào)節(jié)的固定增益，并且輸入或輸出阻抗值符合常用傳輸線特性阻抗。

描述 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.
