General Description
Features
Functional Diagram
Input IP3: +20 dBm
LO to RF Isolation: 35 dB
Hermetic SMT Package, 25 mm2
Screening to MIL-PRF-38535 (Class B or S) Available
Electrical Speci cations, TA = +25° C, LO Drive = +15 dBm*
Typical Applications
The HMC141LH5 is ideal for:
• Telecom Infrastructure
• Military Radio, Radar & ECM
• Space Systems
• Test Instrumentation
The HMC141LH5 is a miniature passive double-
balanced mixer housed in a hermetic SMT leadless
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. The HMC141LH5 allows
the use of surface mount manufacturing techniques
and is suitable for high reliability military, industrial
and space applications.

connected to RF/DC ground.
2RF
This pin is AC coupled and matched to 50 Ohms from
7 - 14 GHz
5IF
This pin is DC coupled. For applications not requiring operation
to DC, this port should be DC blocked externally using a series
capacitor whose value has been chosen to pass the necessary IF
frequency range. For operation to DC, this pin must not source/
sink more than 2 mA of current or die non-function and possible
die failure will result.

Evaluation PCB
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 package base 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.
