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.
