Categories: , Tag: Manufacturer:


400W C-Band TWTA model number VZC-6964 is a wide band amplifier with a range of 5.85 to 6.65 GHz.

This 400W C-Band TWTA has only been in inventory since the first week in February and in our engineers tests it has performed extremely well, the pre-saturation output is 382 watts, which is well within the power range specified by the manufacturer.

The hours and Helix current are at very good levels, showing that even though it is working well now, the indications are that it will work very well for many years to come.

The full test results of the 400W C-Band TWTA can be seen in the downloads tab.

Here is a short excerpt from the data sheet.


Provides 400 watts of power in a 3 rack unit package, digital ready, for wideband, single and
multi-carrier satellite service over any one of several frequency ranges in C-band. Ideal for
transportable and fixed earth station applications where space and prime power are at a premium.


Employs a high efficiency dual-depressed collector helix traveling wave tube backed by
many years of field-proven experience in airborne and military applications.

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.
