HMC442LM1
General Description
Features
Functional Diagram
The HMC442LM1 is a broadband 17.5 to 24 GHz
GaAs PHEMT MMIC Medium Power Ampli er in a
SMT leadless chip carrier package. The LM1 is a true
surface mount broadband millimeterwave package
offering low loss & excellent I/O match, preserving
MMIC chip performance. The ampli er provides
14 dB of gain and +23 dBm of saturated power at
27% PAE from a +5V supply voltage. This 50 Ohm
matched ampli er has integrated DC blocks on RF
in and out and makes an ideal linear gain block,
transmit chain driver or LO driver for HMC SMT mixers.
As an alternative to chip-and-wire hybrid assem-
blies the HMC442LM1 eliminates the need for
wirebonding, thereby providing a consistent con-
nection interface for the customer.
Saturated Power: +23 dBm @ 27% PAE

Typical Applications
The HMC442LM1 is an ideal gain block or driver
ampli er for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios
• VSAT
*Adjust Vgg between -1.5 to -0.5V to achieve Idd = 85 mA typical.
