HMC396

InGaP HBT GAIN BLOCK

MMIC AMPLIFIER, DC - 8 GHz

v02.0109

General Description

Features

Functional Diagram

The HMC396 die is a GaAs InGaP Heterojunction

Bipolar Transistor (HBT) Gain Block MMIC DC to

8 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

HMC396 offers 12 dB of gain and an output IP3 of

+30 dBm while requiring only 56 mA 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 requir-

ing a minimal number of external bias components.

The HMC396 can easily be integrated into Multi-Chip-

data is with the chip in a 50 Ohm test fixture connected

via 0.025mm (1 mil) diameter wire bonds of minimal

length 0.5mm (20 mils).

Gain: 12 dB

P1dB Output Power: +14 dBm

Stable Gain Over Temperature

50 Ohm I/O’s

Small Size: 0.38 x 0.58 x 0.1 mm

Typical Applications

An excellent cascadable 50 Ohm

Gain Block or LO Driver for:

• Microwave & VSAT Radios

• Test Equipment

• Space Telecom
