General Description
The HMC-APH460 is a two stage GaAs HEMT MMIC 0.5 Watt Power Amplifier which operates between 27 and 31.5 GHz. The HMC-APH460 provides 14 dB of gain, and an output power of +28 dBm at 1 dB compression from a +5V supply voltage. All bond pads and the die backside are Ti/Au metallized and the amplifier device is fully passivated for reliable operation. The HMC-APH460 GaAs HEMT MMIC 0.5 Watt Power Amplifier is compatible with conventional die attach methods, as well as thermocompression and thermosonic wirebonding, making it ideal for MCM and hybrid microcircuit applications. All data Shown herein is measured with the chip in a 50 Ohm environment and contacted with RF probes.
