General Description
The HMC395 die is a GaAs InGaP Heterojunction
Bipolar Transistor (HBT) Gain Block MMIC DC - 4
GHz ampli鏗乪r. This ampli鏗乪r die can be used as ei-
ther 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 excellent 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 鏗亁ture connected via 0.025mm (1mil) diameter
wire bonds of minimal length 0.5mm (20mils).
