The CGY2139AUH/C2 is a high performance 3 stages GaAs Power Amplifier MMIC designed to operate in the X band.

The CGY2139AUH has an output power of 12 W at the 1dB compression point and has a small signal gain of 25 dB. It can be used in X-band Radars, Telecommunication and Instrumentation applications.

The MMIC uses gold bonding pads and backside metallization and is fully protected with Silicon Nitride passivation to obtain the highest level of reliability.

The MMIC power dissipation is limited by the die thermal resistance, it has been designed to work in pulse mode, The CGY2139AUH/C2 can be operated at a duty cycle as high as 25%. Drain switch mode is the preferred control mode.

Cascading CGY2139PUH or CGY2139MUH it can form a 50dB gain 12W X-band pulse mode amplifier chain.
