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