Mega Industries manufactures a line of high power waveguide circulators for use in RF applications. Current sizes and configurations are WR-650 to WR-2300. Monitor couplers are provided upon request: -60 +/- 2dB, Type N connector. Circulators are nominally optimized for RF performance at 75kW forward power.
Custom modifications for operation at lower RF power levels are possible upon request. We consider development in all coaxial and waveguide sizes. Additionally, we engineer and fabricate high power circulators with 6-1/8″ coaxial inputs.
Mega developed a proprietary rack-mounted temperature control unit that automatically fine-tunes circulators based on thermal feedback from the cooling circuit.
