Functional Diagram
General Description
The HMC283LM1 is a Medium Power Amplifier (MPA)
in a SMT leadless chip carrier package covering 17
to 40 GHz. The LM1 is a true surface mount broadband
millimeterwave package offering low loss & excel-
lent I/O match preserving MMIC chip performance.
Utilizing a GaAs PHEMT process, the device offers
20 dB gain and +21 dBm output power from a bias
supply of +3.5V @ 300mA. As an alternative to chip-
and-wire hybrid assemblies the HMC283LM1 elimi-
nates the need for wirebonding, thereby providing
a consistent connection interface for the customer.
The amplifier may be used as a frequency doubler.
A built-in-test pad (Vdet) allows monitoring of micro-
wave output power. All data is with the non-hermetic,
epoxy sealed LM1 packaged MPA device mounted in
a 50 ohm test fixture.
