General Notes:
1. The DMF-10A-300 Double Balanced Mixer uses a Class III ring modulator with integral series
RC networks. This yields a mixer with a high third order intercept point across a wide range of
LO power.
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.
