Overview
The HMC633LC4 is a GaAs PHEMT MMIC Driver Amplifier produced by Analog Devices Inc. This amplifier is housed in a leadless 4x4 mm ceramic surface mount package and operates within the frequency range of 5.5 to 17 GHz. It is designed to provide high performance for various microwave radio applications, offering up to 30 dB of gain, +30 dBm Output IP3, and +23 dBm of output power at 1 dB gain compression. The amplifier requires 180 mA from a +5V supply and can be biased at +5V, 130 mA to achieve 2 dB lower gain with improved Power Added Efficiency (PAE).
