HMC338LC3B
v04.0514
GaAs MMIC SUB-HARMONIC
SMT MIXER, 24 - 34 GHz
General Description
Features
Functional Diagram
The HMC338LC3B is a 24 - 34 GHz Sub-harmonically
Pumped (x2) MMIC Mixer with an integrated LO
amplier in a leadless RoHS compliant 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
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.
Integrated LO Amplier: -5 dBm Input
Sub-Harmonically Pumped (x2) LO
DC - 3 GHz Wideband IF
Single Positive Supply: +4V @ 31mA
12 Lead 3x3mm SMT Package: 9mm²
Electrical Specications, TA = +25 °C, As a Function of Vdd
Typical Applications
The HMC338LC3B is ideal for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios & VSAT
• Test Equipment & Sensors
• Military End-Use
• SAT COM

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.
