The CMD247 is a wideband GaAs MMIC low

phase noise amplifier ideally suited for mili-

tary, space and communications systems. At

35 GHz the device delivers 13 dB of gain, a

saturated output power of +15 dBm and a noise

figure of 5 dB. Also the amplifier provides low

phase noise of less then -160 dBc/Hz at 10 kHz

offset. The CMD247 is a 50 ohm matched de-

sign which eliminates the need for external DC

blocks and RF port matching. The CMD247

offers full passivation for increased reliability

and moisture protection.

► Wide bandwidth

► Low phase noise

► Low current consumption

► Small die size
