Electrical Speci cations, TA = +25° C, LO Drive = +10 dBm
Typical Applications
The HMC171C8 is ideal for:
• Microwave Point-to-Point Radios
• 5.8 GHz ISM Band Circuits
The HMC171C8 is a miniature double-balanced mixer
in a non-hermetic ceramic surface mount package
that can be used as an upconverter, downconverter
or biphase modulator. The device is a passive diode/
balun type mixer with high dynamic range. Noise gure
is essentially equal to the conversion loss. 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 consistency. This mixer has applications
in circuits where small size and surface mount
compatibility are important.

Evaluation PCB
Item Description
J1 - J3 PCB Mount SMA RF Connector
U1 HMC171C8 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.
