SiGe HBT GAIN BLOCK

MMIC AMPLIFIER, DC - 6 GHz

v01.0505

General Description

Features

Functional Diagram

The HMC476MP86 & HMC476MP86E are 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 as well as a

LO or PA driver with up to +13 dBm output power.

The HMC476MP86 & HMC476MP86E offers 20 dB

of gain with a +25 dBm output IP3 at 850 MHz while

requiring only 35 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.

P1dB Output Power: +12 dBm

Gain: 20 dB

Output IP3: +25 dBm

Cascadable 50 Ohm I/Os

Single Supply: +5V to +12V

Included in the HMC-DK001 Designer’s Kit

Typical Applications

The HMC476MP86 / HMC476MP86E is an ideal RF/

IF gain block & LO or PA driver for:

• Cellular / PCS / 3G

• Fixed Wireless & WLAN

• CATV, Cable Modem & DBS

• Microwave Radio & Test Equipment
