DC Offset Voltage: 8 mV typ. Weight: 0.1 oz (2.8 g) Operating Temperature:– 55° to +85°C 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. 29Apr96 For further information contact MERRIMAC/ 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531
