General Description
The HMC268LM1 is a two stage GaAs MMIC Low
Noise Amplifier (LNA) in a SMT leadless chip carrier
package covering 20 to 32 GHz. The LM1 is a true
surface mount broadband millimeterwave package
offering low loss & excellent I/O match, preserving
MMIC chip performance. Utilizing a GaAs PHEMT
process the device offers 2.6 dB noise figure, 15 dB
gain and +13 dBm output power from a bias supply
of +4V @ 45 mA. As an alternative to chip-and-wire
hybrid assemblies the HMC268LM1 eliminates the
need for wirebonding, thereby providing a consis-
tent connection interface for the customer. All data
is with the non-hermetic, epoxy sealed LM1 pack-
aged LNA device mounted in a 50 ohm test fixture.
