The HMC634 is a GaAs MMIC PHEMT Driver Amplifier die which operates between 5 and 20 GHz. The amplifier provides up to 22 dB of gain, +31 dBm Output IP3, and up to +23 dBm of output power at 1 dB gain compression, while requiring 180 mA from a +5V supply. The HMC634 is an ideal driver amplifier for microwave radio applications from 5 to 20 GHz, and may be biased at +5V, 130 mA to provide 2 dB lower gain with improved PAE. The HMC634 amplifier I/O’s are DC blocked and internally matched to 50 Ohms facilitating easy integration into Multi-Chip-Modules (MCMs). All data is taken with die connected at input and output RF ports via one 1 mil wedge bond with minimal length of 0.31 mm (12 mils).
