HMC395
InGaP HBT GAIN BLOCK
MMIC AMPLIFIER, DC - 4 GHz
V02.0109
General Description
Features
Functional Diagram
The HMC395 die is a GaAs InGaP Heterojunction Bi-
polar Transistor (HBT) Gain Block MMIC DC - 4 GHz
ampli er. This ampli er die can be used as either a
cascadable 50 Ohm gain stage or to drive the LO of
HMC mixers with up to +17 dBm output power. The
HMC395 offers 16 dB of gain and an output IP3 of +31
dBm while requiring only 54 mA 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 (0.22mm
2
) size. All
data is with the chip in a 50 Ohm test xture connected
via 0.025mm (1mil) diameter wire bonds of minimal
length 0.5mm (20mils).
