HMC264LC3B
v04.0414
GaAs MMIC SUB-HARMONIC
SMT MIXER, 21 - 31 GHz
General Description
Features
Functional Diagram
The HMC264LC3B is a 21 - 31 GHz Sub-harmonically
Pumped (x2) MMIC Mixer with an integrated LO
amplier in a leadless “Pb Free” SMT package. The
2LO to RF isolation is excellent at 30 dB, eliminating
the need for additional ltering. The LO amplier is
a single bias (+3V to +4V) design with only -4 to +4
dBm drive requirement. The RF and LO ports are DC
blocked and matched to 50 Ohms for ease of use
while the IF covers DC to 6 GHz. The HMC264LC3B
eliminates the need for wire bonding, allowing use of
surface mount manufacturing techniques.
Integrated LO Amplier: -4 to +4 dBm Input

Pin Descriptions
Pin Number Function Description Interface Schematic
1Vdd Power supply for the LO Amplier. External RF bypass capacitors
are required as close to the package as possible.
2, 3 N/C No connection required. These pins may be connected to RF/DC
ground without affecting performance.
4, 6, 7,
9, 10, 12 GND Package bottom must also be connected to RF/DC ground.
5LO LO Port. This pin is AC coupled and matched to
50 Ohms from 10.5 - 15.5 GHz.
8IF
IF Port. This pin is DC coupled and should be DC blocked exter-
nally using a series capacitor whose value has been chosen to pass
the necessary IF frequency range. Any applied DC voltage to this
pin will result in die non-function and possible die failure.
11 RF RF Port. This pin is AC coupled and matched to
50 Ohms from 21 - 31 GHz.

[2] Circuit Board Material: Rogers 4350
The circuit board used in this application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation board should be mounted to an appro-
priate heat sink. The evaluation circuit board shown
is available from Hittite upon request.
