2000 MHz and is ideal for general applications. Other models available in

surface mount packages are electrically similar to the standard flatpack units

but have extended frequency range up to 3.6 GHz with proportionately fast

risetimes.

2. Customized versions are available for special frequency bands matched to

your special applications. Most units are available in a variety of alternative

packages such as the TO-8, flatpack or connectorized packages. TTL or ECL

drivers can be provided in the larger packages.

3. Merrimac Biphase Modulators cover a variety of frequency bands while

providing wide bandwidths suitable for most applications.

4. All units comply with applicable sections MIL-M-28837 and may be supplied

screened for compliance with additional specifications for military and space

applications requiring the highest reliability.
