The CMD249 is wideband GaAs MMIC dis-

tributed power amplifier die which operates

from DC to 20 GHz. The amplifier delivers

greater than 12 dB of gain with a correspond-

ing output 1 dB compression point of +30 dBm

and output IP3 of 38 dBm at 10 GHz. The

CMD249 is a 50 ohm matched design which

eliminates the need for RF port matching. The

CMD249 offers full passivation for increased

reliability and moisture protection.

► Ultra wideband performance

► High linearity

► High output power

► Excellent return losses

► Small die size
