Functional Diagram
General Description
The HMC329LM3 is a 26 - 40 GHz surface mount,
passive, double-balanced MMIC mixer in a SMT lead-
less chip carrier package. The mixer can be used as
a downconverter or upconverter. Excellent isolations
are provided by on-chip baluns. The chip requires no
external components and no DC bias. All data is with
the non-hermetic, epoxy sealed LM3 package mounted
in a 50 Ohm test fixture. Utilizing the HMC329LM3
eliminates the need for wirebonding, thereby providing
a consistent connection interface for the customer.

MIXERS - SMT
This pin is DC coupled and matched to
50 Ohm from 25 to 40 GHz.
5
IF
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 or sink more than 2 mA of cur-
rent or part non-function and possible part failure will result.

LO
This pin is DC coupled and matched to
50 Ohm from 25 to 40 GHz.
GND
Package base must be soldered to PCB RF ground.
