Compact, sturdy power tubes for high linearity VHF-TV equipment as well as other CW or pulsed RF applications
DESCRIPTION
Designed for high gain, high linearity VHF-TV equipment, Photonis Defense’s VHF Commercial Tubes are easily circuited to a frequency required by your requirement. The coaxial-terminal design of the tubes assures a high gain bandwidth product for the full VHF-TV band as well as the added ability for operation in the TEM Mode. Photonis’ VHF Commercial tubes are sturdy, operate well in high temperatures and offer minimized tube inductances. This makes it possible to use simple, economical, broadband circuit techniques in applications requiring VHF operation. Besides commercial VHF-TV service, Photonis’ VHF Commercial tubes are also well suited for other applications such as; single side band, CW or pulsed RF, modulator services, translator services and much more.
Power Tube Cavities
For many years, Photonis Defense has been developing specialized circuitry for power tubes, generally termed “cavities” as a result of customer demand. These cavities are complete RF circuits that are necessary to tune and operate a matching power tube. Each cavity is designed to match a specific tube in order to produce a final high-power amplifier stage for a specific frequency band and service. Each cavity is an essential part of the installation and maintenance operations needed for a Photonis Defense Power Tube. Photonis Defense highly recommends pairing one of our cavities with any recommended matching power tube and can work with you to determine which power tube cavity your application requires.
