(50% Control to 90% RF) ECL compatible (terminated or unterminated) – 5.2 VDC (@ 40 mA nom.) – 55° to +85°C AVAILABLE OPTIONS Direct (No Driver) Integral TTL Driver: Other frequencies: As BPM series As BTM series Up to 2500 MHz. Consult with factory General Notes: 1. The BEM and BETM-2A series of Biphase Modulators cover the frequency range of 2 to 2000 MHz and can be driven directly by standard ECL using only a – 5.2 V supply. Custom units covering up to 2500 MHz may be obtained. Consult with the factory. 2. The BEM-2A series requires an external 50Ω logic input termination while the BETM-2A series includes an internal 50Ω logic input termination. Comparable TTL versions are available in a similar package or a non-connectorized Meri-Pac ™ or flatpack (see BTF-2A series). Units without integral TTL drivers are available in the BPM-2A series. 3. Merrimac Biphase Modulators cover a variety of frequency bands while providing wide bandwidths suitable for most applications. 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 F r furt her inform tion cont act MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / o a 973-575-1300 / FAX 973-575-0531
