All specifications are as measured in a 50

Ω system, at nominal LO power, in a down converter application.

General Notes:

1. The DMG-A series of surface mount Double Balanced Mixers covers

the frequency range of 10 to 1500 MHz using miniature 4-diode rings

suitable for both general purpose and high performance applications.

2. The DMG-A SMD package is designed for 50

Ω coplanar systems

to insure satisfactory RF performance. The Kovar leads are supplied

untrimmed (unless otherwise specified) to allow mounting the package

in a variety of configurations.

3. Merrimac offers a broad selection of Double Balanced Mixers ideal

for a variety of signal processing functions from 20 kHz to 20 GHz.

4. Merrimac mixers comply with MIL-M-28837 and may be supplied

screened for compliance with additional specifications for military and

space applications requiring the highest reliability.
