HMC397
InGaP HBT GAIN BLOCK
MMIC AMPLIFIER, DC - 10 GHz
v03.0109
General Description
Features
Functional Diagram
The HMC397 die is a GaAs InGaP Heterojunction
Bipolar Transistor (HBT) Gain Block MMIC DC to
10 GHz ampli er. This ampli er can be used as either
a cascadable 50 Ohm gain stage or to drive the
LO of HMC mixers with up to +16 dBm output power.
The HMC397 offers 15 dB of gain and an output
IP3 of +32 dBm while requiring only 56 mA from a
+5V supply. The Darlington feedback pair used re-
sults in reduced sensitivity to normal process
variations and yields excellent gain stability over
temperature while requiring a minimal number of
external bias components. The HMC397 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
(1 mil) diameter wire bonds of minimal length 0.5mm
(20 mils).
