The CMD299 is a highly efficient GaAs

MMIC low noise amplifier ideally suited for

EW and communications systems where small

size and low power consumption are needed.

The device is optimized for 30 GHz and

delivers greater than 17 dB of gain with a

corresponding noise figure of 3.5 dB and

output 1 dB compression point of +7 dBm. The

CMD299 is a 50 ohm matched design which

eliminates the need for external DC blocks and

RF port matching. The CMD299 offers full

passivation

for

increased

reliability

and

moisture protection.

► Low noise performance

► Wide bandwidth

► All positive supply voltages

► Low current consumption

► Small die size
