VZU-6997AD-L - Communications & Power Industries

750 W Peak Compact High Power Amplifier
Provides 290 watts of linear output power in a 5 rack unit
package, digital ready, for wideband, single- and multi-carrier
satellite service in the 13.75-14.50 GHz frequency band. Ideal
for transportable and fixed earth station applications
where space and prime power are at a premium.
Employs a high efficiency peak power TWTA. This HPA
consumes about half the power of competing SSPAs, and
is signifi cantly more efficient than 750 W CW
dual-collector TWTAs.
Simple to Operate
User-friendly microprocessor-controlled logic with integrated
computer interface, digital metering, pin diode attenuation
and optional integrated linearizer for improved
intermodulation performance.
Global Applications
Meets International Safety Standard EN-60215,
Electromagnetic Compatibility 2004/108/EC and Harmonic
Standard EN-61000-3-2 to satisfy worldwide requirements.
