The CMD245 is a wideband GaAs MMIC low

phase noise amplifier ideally suited for mili-

tary, space and communications systems. At

10 GHz the device delivers 18 dB of gain, a

saturated output power of +21 dBm and a noise

figure of 3 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 CMD245 is a 50 ohm matched design

which eliminates the need for RF port match-

ing. The CMD245 offers full passivation for

increased reliability and moisture protection.

► Wide bandwidth

► Low phase noise

► Low current consumption

► Small die size
