Microsemi MMA053AA GaAs power amplifier

The Microsemi MMA053AA is a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) pHEMT distributed power amplifier die that operates between DC and 8 GHz.

The amplifier provides 17 dB of gain, +43 dBm output IP3 and +31 dBm of output power at 3 dB compression, while requiring only 410 mA from an 11 V supply. Gain flatness over the DC to 8 GHz frequency range varies by only ±0.5 dB, making the die suitable for EW, ECM, radar and test equipment applications.

The product features compact die size (3 x 2.25 x 0.07 mm) and I/Os that are internally matched to 50Ω, facilitating easy integration into multichip modules (MCMs). Its high performance capabilities offer users a way to meet demanding system and module line-up requirements with minimal DC power consumption.
