The CMD274 is a wideband GaAs MMIC low

phase noise amplifier die that is ideally suited

for

military,

space

and

communications

systems. At 10 GHz the device delivers 17 dB

of gain, a saturated output power of +22 dBm

and a noise figure of 3.2 dB. Also with an input

signal of 10 GHz the amplifier provides low

phase noise performance of -165 dBc/Hz at 10

kHz offset. The CMD274 is a 50 ohm matched

design which eliminates the need for external

DC blocks and RF port matching.

► Ultra wideband performance

► Low phase noise

► Low current consumption

► Small die size
