Functional Diagram
General Description
The HMC798LC4 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 +5V design with a
nominal +4 dBm drive requirement. The RF and
LO ports are matched to 50 Ohms for ease of
use while the IF covers DC to 4 GHz. The HMC798LC4
eliminates the need for wire bonding, allowing use of
surface mount manufacturing techniques.

Evaluation PCB

[1]
List of Materials for Evaluation PCB 126601
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.
