Typical Applications
The HMC329LM3 is ideal for:
Point-to-Point Radios
Point-to-Multi-Point Radios
SATCOM
RADAR
* Unless otherwise noted, all measurements performed as downconverter, IF= 1 GHz.
The HMC329LM3 is a 26 - 40 GHz surface mount,
passive, double-balanced MMIC mixer in a SMT
leadless 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 fi xture. Utilizing
the HMC329LM3 eliminates the need for wirebond-
ing, thereby providing a consistent connection inter-
face for the customer.

N/C
This pin may be connected to the PCB ground
or left unconnected.
4
RF Port
This pin is DC coupled and matched to 50 Ohm
from 25 to 40 GHz.
5
IF Port
This pin is DC coupled. For applications not requiring opera-
tion 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 current or part
non-function and possible part failure will result.
6
LO Port
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.
