Functional Diagram
General Description
The HMC170C8 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
figure 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 applica-
tions where small size and surface mount compatibil-
ity are important.

[2] Circuit Board Material: Rogers 4350
The circuit board used in the final 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.
