HMC519

GaAs PHEMT MMIC LOW NOISE

AMPLIFIER, 18 - 32 GHz

v00.0904

General Description

Features

Functional Diagram

The HMC519 chip is a high dynamic range GaAs

PHEMT MMIC Low Noise Amplifier (LNA) which

covers the 18 to 32 GHz frequency range. The

HMC519 provides 15 dB of small signal gain, 2.8 dB

of noise figure and has an output IP3 greater than

23 dBm. The chip can easily be integrated into hy-

brid or MCM assemblies due to its small size. All data

is tested with the chip in a 50 Ohm test fixture con-

nected via 0.075 mm (3 mil) ribbon bonds of minimal

length 0.31 mm (12 mil). Two 0.025 mm (1 mil) diameter

bondwires may also be used to make the RFIN and

RFOUT connections.

Noise Figure: 2.8 dB

Gain: 15 dB

OIP3: 23 dBm

Single Supply: +3V @ 65 mA

50 Ohm Matched Input/Output

Typical Applications

The HMC519 is ideal for use as either a LNA or driver

amplifier for:

• Point-to-Point Radios

• Point-to-Multi-Point Radios & VSAT

• Test Equipment & Sensors

• Military & Space
