The CMD291 is a wideband GaAs MMIC driver

amplifier die which operates from 16 to 24 GHz.

The broadband device is ideally suited for

applications requiring high dynamic range. The

CMD291 delivers 23 dB of gain with a

corresponding output 1 dB compression point of

+25.5 dBm and output IP3 of 32 dBm at 20 GHz.

The amplifier is a 50 ohm matched design which

eliminates the need for external DC blocks and

RF port matching. The CMD291 offers full

passivation for increased reliability and moisture

protection.
