Electrical Speci cations, TA = +25° C, LO Drive = +15 dBm
Typical Applications
The HMC141C8 is ideal for:
• Microwave Point-to-Point Radios
• VSAT Ground Equipment
The HMC141C8 is a miniature passive 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 of 20 dBm. MMIC
implementation provides exceptional balance in the
circuit resulting in high LO/RF and LO/IF isolations and
unit-to-unit consistency. This mixer has applications
where small size and surface mount compatibility are
important.

Evaluation PCB
List of Materials for Evaluation PCB 102102 [1]
Item Description
J1 - J3 PCB Mount SMA RF Connector
U1 HMC141C8 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.
