Analog Devices HMC659LC5 MMIC Power Amplifiers are gallium arsenide (GaAs) radio-frequency devices designed for surface-mount technology (SMT) packages. The amplifier operates between direct current and 15GHz, making it ideal for radar and test equipment applications. The Monolithic Microwave Integrated Circuit device is housed in a leadless 5mm x 5mm RoHS-compliant ceramic SMT package. The pseudomorphic-high-electron-mobility-transistor (pHEMT) amplifier provides 19dB of gain, +35dBm output IP3, and +27.5dBm of output power at 1dB gain compression while requiring 300mA from a +8V supply. The HMC659 amplifier input/output is internally matched to 50Ω, facilitating integration into multi-chip modules (MCMs).
