HMC490

v03.0213

GaAs pHEMT MMIC LOW NOISE

HIGH IP3 AMPLIFIER, 12 - 17 GHz

General Description

Features

Functional Diagram

The HMC490 is a high dynamic range GaAs

PHEMT MMIC Low Noise Amplifier which operates

between 12 and 17 GHz. The HMC490 provides

27 dB of gain, 2 dB noise figure and an output IP3

of 35 dBm from a +5V supply voltage. The amplifier

chip can easily be integrated into Multi-Chip-Modules

(MCMs) due to its small size. All data is tested with

the chip in a 50 Ohm test fixture connected via

0.025mm (1 mil) diameter wire bonds of minimal length

0.31mm (12 mils).

Noise Figure: 2 dB

Output P1dB: +26 dBm

Gain: 27 dB

Output IP3: +35 dBm

Supply Voltage: +5V

50 Ohm Matched Input/Output

Die Size: 2.78 x 1.46 x 0.1 mm

Typical Applications

The HMC490 is ideal for use as either a LNA or driver

amplifier for:

• Point-to-Point Radios

• Point-to-Multi-Point Radios

• VSAT

• Military & Space
