Input IP3: 20 dBm
Conversion Loss: 8.5 dB
LO to RF Isolation: 35 dB
Electrical Speci cations, TA = +25° C, LO Drive = +15 dBm
Typical Applications
The HMC142C8 is ideal for:
• Microwave Point-to-Point Radios
• VSAT Ground Equipment
The HMC142C8 is a miniature double-balanced mixer
in a non-hermetic ceramic surface mount package
that can be used as an upconverter or downconverter.
The device is a passive diode/balun type mixer with
high dynamic range. The mixer can handle larger
signal levels than most active mixers due to the high
third order intercept. MMIC implementation provides
exceptional balance in the circuit resulting in high
LO/RF and LO/IF isolations and unit-to-unit consis-
tency. This mixer has applications where small size
and surface mount compatibility are important.

Evaluation PCB
Item Description
J1 - J3 PCB Mount SMA RF Connector
U1 HMC142C8 Mixer
PCB [2] 107214 Evaluation Board
[1] Reference this number when ordering complete evaluation PCB
[2] Circuit Board Material: Rogers 4350
The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected 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.
