RF/IF Isolation: 15 dB
IF Bandwidth: DC - 4 GHz
Downconverter Applications
12 Lead Ceramic 3 x 3 mm SMT Package: 9 mm2
Typical Application
The HMC1048LC3B is ideal for:
• Ka-band Transponders
• Point-to-Multi-Point Radios & VSAT
• Test Equipment & Sensors
• Military End-Use
General Description
The HMC1048LC3B is a general purpose double
balanced mixer that can be used as a downconverter
with DC to 4 GHz at the IF port and 2 to 18 GHz at the
RF port. This mixer requires no external components
or matching circuitry. The HMC1048LC3B provides
excellent LO/RF, LO/IF and RF/IF isolation The
mixer operates with LO drive levels from +9 dBm to
+17 dBm. The HMC1048LC3B eliminates the need
for wire bonding and allows the use of surface mount
manufacturing techniques.

The circuit board used in the 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 circuit board shown is available from
Hittite upon request.
