SiGe HBT GAIN BLOCK

MMIC AMPLIFIER, DC - 6 GHz

v01.0906

General Description

Functional Diagram

The HMC474MP86 & HMC474MP86E are general

purpose SiGe Heterojunction Bipolar Transistor (HBT)

Gain Block MMIC SMT amplifiers covering DC to 6

GHz. This Micro-P packaged amplifier can be used

as a cascadable 50 Ohm RF/IF gain stage with up to

+10 dBm output power. The HMC474MP86(E) offer

15.5 dB of gain with a +22 dBm output IP3 at 850

MHz while requiring only 25 mA from a single positive

supply. The Darlington feedback pair used results in

reduced sensitivity to normal process variations and

excellent gain stability over temperature while requiring

a minimal number of external bias components.

Gain: 15.5 dB

P1dB Output Power: +8 dBm

Output IP3: +22 dBm

Cascadable 50 Ohm I/Os

Single Supply: +3V to +10V

Included in the HMC-DK001 Designer’s Kit

Typical Applications

The HMC474MP86 & HMC474MP86E is an ideal

RF/IF gain block for:

• Cellular / PCS / 3G

• Fixed Wireless & WLAN

• CATV, Cable Modem & DBS

• Microwave Radio & Test Equipment
