HMC481MP86

SiGe HBT GAIN BLOCK

MMIC AMPLIFIER, DC - 5.0 GHz

v00.0603

General Description

Features

Functional Diagram

The HMC481MP86 is a SiGe Heterojunction Bipolar

Transistor (HBT) Gain Block MMIC SMT amplifier

covering DC to 5 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 +21 dBm output power. The HMC481MP86

offers 20 dB of gain with a +33 dBm output IP3

at 850 MHz while requiring only 74 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: +19 dBm

Gain: 20 dB

Output IP3: +33 dBm

Cascadable 50 Ohm I/Os

Single Supply: +6V to +12V

Typical Applications

The HMC481MP86 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

Note: Data taken with broadband bias tee on device output.
