A high performance, low loss series of circulators and isolators cover TV channels 7-78 (174-860 MHz) Power ratings are 500 watts power (type N) or 1 Kw (DIN 7/16).
HIGH POWER – Six high performance units give coverage for the VHF Channels 7 – 13 and UHF TV Bands 7 – 78. Optimized for LOW LOSS, these circulators are rated at 500 Watts average , 3 Kilowatts peak with N connectors and 1 KW average and 5 KW peak with DIN 7/16 connectors.
Designed for efficient heat transfer, additional heat sinking may be required where high reverse power is expected. Keeping the body temperature within the rated temperature range of -10 to +70 degrees C is recommended.
The isolator version has an integral 125 watt load designed to provide a minimum of 20 dB isolation.
MEDIUM POWER – These units cover most common UHF frequency ranges at power levels of 100 watts CW or average. They are also available for any specific frequencies you designate.
