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 amplifier. This amplifier 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

variations and yields excellent gain stability over

temperature while requiring a

of

external bias components. The HMC397 can easily

be integrated into Multi-Chip-Modules (MCMs) due

in a 50 Ohm test fixture connected via 0.025mm

(1 mil) diameter wire bonds of minimal length 0.5mm

(20 mils).

Gain: 15 dB

P1dB Output Power: +15 dBm
