General Description

Functional Diagram

The HMC471MS8G & HMC471MS8GE are SiGe HBT

Dual Channel Gain Block MMIC SMT amplifiers cov-

ering DC to 5 GHz. These versatile products contain

two gain blocks, packaged in a single 8 lead plas-

tic MSOP, for use as either separate cascadable 50

Ohm RF/IF gain stages, LO or PA drivers or with both

amplifiers combined utilizing external 90° hybrids to

create a high linearity driver amplifier. Each ampli-

fier in the HMC471MS8G(E) offers 20 dB of gain,

+20 dBm P1dB with a +34 dBm output IP3 at 850

MHz while requiring only 80 mA from a single positive

supply. The combined dual amplifier circuit delivers

up to +21 dBm P1dB with +36 dBm OIP3 for specific

application bands through 4 GHz.

P1dB Output Power: +20 dBm

Gain: 20 dB

Output IP3: +34 dBm

Supply (Vs): +6V to +12V

Typical Applications

The HMC471MS8G / HMC471MS8GE is a dual RF/IF

gain block & LO or PA driver:

• Cellular / PCS / 3G

• Fixed Wireless & WLAN

• CATV, Cable Modem & DBS

• Microwave Radio & Test Equipment

Note: Data taken with broadband bias tee on device output. All specifications refer to a single amplifier.
