General Notes:
1. The DMF-12A series of Double Balanced Mixers covers the frequency range of of 0.5 to 2000 MHz using a 12 diode ring modulator to produce
an extremely high level mixer with high third order intercept points.
2. Merrimac offers a broad selection of Double Balanced Mixers ideal for a variety of signal processing functions with frequencies ranging from
20 kHz to 20 GHz.
3. 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.
