GaAs MMIC Driver Amplifier offers high output, low consumption.

Press Release Summary:

Supplied in leadless, RoHS-compliant, 4 x 4 mm, SMT package, CMD191C4 operates from 4–10 GHz and delivers 20 dB of gain with corresponding output 1 dB compression point of >+21 dBm. This GaAs MMIC (monolithic microwave integrated circuit) driver amplifier is 50Â Ω matched design, which eliminates need for external DC blocks and RF port matching. RF power can be applied at any time, and device is biased with single 5.0 V positive drain supply.

Original Press Release:

New 4-10 GHz Driver Amplifier Offers High Output Power, Low Current Consumption

Westford, MA – Custom MMIC (, a developer of performance-driven monolithic microwave integrated circuits (MMICs), announces the addition of the CMD191C4 to their growing MMIC library of standard products.

The CMD191C4 is a GaAs MMIC driver amplifier housed in a leadless, RoHs compliant, 4x4 mm surface mount package. It offers high output power and low current consumption. Ideally suited for complex communications systems where small size and high linearity are needed, the device operates from 4-10 GHz and delivers 20 dB of gain with a corresponding output 1 dB compression point of greater than +21 dBm. It is a 50 ohm matched design, which eliminates the need for external DC blocks and RF port matching.

The CMD191C4 is biased with a single 5.0 V positive drain supply. RF power can be applied at any time. Suitable applications include WiLAN, C and X Band communications systems, and military end-use.
