HMC326MS8G / 326MS8GE

v09.0511

GaAs InGaP HBT MMIC DRIVER

AMPLIFIER, 3.0 - 4.5 GHz

General Description

Features

Functional Diagram

The HMC326MS8G & HMC326MS8GE are high

efficiency GaAs InGaP Heterojunction Bipolar

Transistor (HBT) MMIC driver amplifiers which

operate between 3.0 and 4.5 GHz. The amplifier

is packaged in a low cost, surface mount 8 leaded

package with an exposed base for improved RF and

thermal performance. The amplifier provides 21 dB

of gain and +26 dBm of saturated power from a +5V

supply voltage. Power down capability is available to

conserve current consumption when the amplifier is

not in use. Internal circuit matching was optimized to

provide greater than 40% PAE.

Psat Output Power: +26 dBm

> 40% PAE

Output IP3: +36 dBm

High Gain: 21 dB

Vs: +5V

Ultra Small Package: MSOP8G

Typical Applications

The HMC326MS8G / HMC326MS8GE is ideal for:

• Microwave Radios

• Broadband Radio Systems

• Wireless Local Loop Driver Amplifier
