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.
