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 50 logic input termination while the BETM-2A series includes an internal 50 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.
