Tiny MMIC amplifier delivers high linearity for military, space, and communications systems

Custom MMIC has announced the CMD207, a 20 to 40 GHz MMIC driver amplifier in die form with an all positive bias scheme, to their growing list of standard products.

The CMD207 delivers 25 to 30 dB of gain, has an output 1 dB compression point of +18.5 dBm, a saturated output power of +21 dBm, and a noise figure of 5 to 6 dB across the entire 20 to 40 GHz bandwidth. The amplifier utilizes an all-positive bias scheme of 4.0 V, 270 mA on the drain, and 3 V, 3 mA on the gate, thereby eliminating the need for a negative voltage and costly bias sequencing circuitry.

The CMD207 is a matched 50 Ohm design and does not require any external components except for bypass capacitors. The die is fully passivated for increased reliability and moisture protection.

Ideal applications for the CMD207 are point-to-point and point-to-multipoint radios, VSAT, and military and space.
