HMC498LC4

v05.0418

GaAs PHEMT MEDIUM

POWER AMPLIFIER, 17 - 24 GHz

Typical Applications

Features

The HMC498LC4 is ideal for use as a LNA or Driver

ampliﬁer for:

Output IP3: +36 dBm

Saturated Power: +26 dBm @ 23% PAE

50 Ohm Matched Input/Output

RoHS Compliant 4x4 mm SMT Package

Functional Diagram

General Description

The HMC498LC4 is a high dynamic range GaAs

PHEMT MMIC Medium Power Ampliﬁer housed in a

leadless “Pb free” SMT package. Operating from 17

to 24 GHz, the ampliﬁer provides 22 dB of gain, +26

dBm of saturated power and 23% PAE from a +5V

supply voltage. Noise ﬁgure is 4 dB while output IP3 is

+36 dBm typical enabling the HMC498LC4 to function

as a low noise front end as well as a driver ampliﬁer.

The RF I/Os are DC blocked and matched to 50 Ohms

for ease of use. The HMC498LC4 eliminates the

need for wire bonding, allowing use of surface mount

manufacturing techniques.
