General Description
The HMC395 die is a GaAs InGaP Heterojunction Bi-
polar Transistor (HBT) Gain Block MMIC DC - 4 GHz
amplifier. This amplifier die can be used as either a
cascadable 50 Ohm gain stage or to drive the LO of
HMC mixers with up to +17dBm output power. The
HMC395 offers 16 dB of gain and an output IP3 of
+31dBm while requiring only 54mA from a +5V supply.
The Darlington feedback pair used results in reduced
sensitivity to normal process variations and yields ex-
cellent gain stability over temperature while requiring
a minimal number of external bias components. The
HMC395 can easily be integrated into Multi-Chip-
Modules (MCMs) due to its small (0.22mm²) size. All
data is with the chip in a 50 Ohm test fixture connected
via 0.025mm (1mil) diameter wire bonds of minimal
length 0.5mm (20mils).
