Functional Diagram
General Description
The HMC264LM3 is a 20 - 30 GHz surface mount
sub-harmonically pumped (x2) MMIC mixer with an
integrated LO amplifier in a SMT leadless chip car-
rier package. The 2LO to RF isolation is an excel-
lent 25 to 35 dB, eliminating the need for additional
filtering. The LO amplifier is a single bias (+3V to +4V)
two stage design with only -4 dBm drive requirement.
All data is with the non-hermetic, epoxy sealed LM3
packaged device mounted in a 50 ohm test fixture.
Utilizing the HMC264LM3 eliminates the need for
wirebonding, thereby providing a consistent connec-
tion interface for the customer.

Description
This pin may be connected to the housing
ground or left unconnected.
Power supply for the LO Amplifier. An external RF bypass capacitor
of 100 - 330 pF is required as close to the package as possible.
This pin is AC coupled an matched to
50 Ohm from 20 - 30 GHz.

IF
This pin is DC coupled and should be DC blocked externally using
a series capacitor whose value has been chosen to pass the neces-
sary IF frequency range. Any applied DC voltage to this pin will
result in die non-function and possible die failure.

LO
This pin is AC coupled and matched to
50 Ohm from 10 - 15 GHz.

GND
Must be soldered to PCB RF ground.
