General Description
The HMC459 is a GaAs MMIC PHEMT Distributed
Power Amplifier die which operates between DC
and 18 GHz. The amplifier provides 17 dB of gain,
+31.5 dBm output IP3 and +25 dBm of output power
at 1 dB gain compression while requiring 290 mA
from a +8V supply. Gain flatness is good making the
HMC459 ideal for EW, ECM and radar driver amplifier
applications. The HMC459 amplifier I/O’s are inter-
nally matched to 50 Ohms facilitating easy integration
into Multi-Chip-Modules (MCMs). All data is with the
chip in a 50 Ohm test fixture connected via 0.025mm
(1 mil) diameter wire bonds of minimal length 0.31mm
(12 mils).
