Switching Speed: 5 nS typ. 50% Control to 90% RF Data Signal Levels: TTL compatible Power Supply: +5 VDC @ 25 mA Weight, nominal: 1.5 oz (42 g) Operating Temp: – 55° to +85°C AVAILABLE OPTIONS NOTES: 1. Tolerance on 3 place decimals ± 0.020" (0.51 mm), except as noted. 2. Dimensions in inches over mm. Direct Input (No driver): As BPM series Integral ECL Driver: As BEM series General Notes: 1. The BTM-2A series of Biphase Modulators covers the frequency range of 2 to 2500 MHz and includes interfacing circuitry so units may be driven directly using a +5V supply. 2. Customized versions are available for special frequency bands matched to your special applications. 3. Most units in this series are available in a variety of alternative packages such as the Meri-Pac or flatpack (see BTF-2A series). Units supplied without integral TTL drivers are available in the BPM-2A series. 4. All units comply with the applicable sections of MIL-M-28837 and may be supplied screened for compliance with additional specifications for military and space applications requiring the highest reliability. 22Feb96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531
