HMC634
GaAs PHEMT MMIC DRIVER
AMPLIFIER, 5 - 20 GHz
v01.0308
General Description
Features
Functional Diagram
The HMC634 is a GaAs MMIC PHEMT Driver
Ampli er die which operates between 5 and 20 GHz.
The ampli er 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 ampli er 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 ampli er 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).
