Functional Diagram
General Description
The HMC338LC3B is a 24 - 34 GHz Sub-harmonically
Pumped (x2) MMIC Mixer with an integrated LO
amplifier in a leadless RoHS compliant SMT package.
The 2LO to RF isolation is excellent at 30 dB,
eliminating the need for additional filtering. The LO
amplifier is a single bias (+3V to +4V) design with
a nominal -5 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 3 GHz.
The HMC338LC3B eliminates the need for
wire bonding, allowing use of surface mount
manufacturing techniques.

IF
This pin is DC coupled and should be DC blocked externally 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.

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 appropriate heat sink. The evaluation circuit board shown
is available from Hittite upon request.
