Mega Industries manufactures its line of high power waveguide circulators for use in RF applications. Our circulators are custom configured to each specific customers’ application. Current sizes and configurations are WR-650 to WR-2300. However, Mega considers circulator development in all coaxial and waveguide sizes. We also offer high power Coaxial Circulators with 6-1/8″ Coaxial Inputs.Buy Online
Mega developed a proprietary rack-mounted temperature control unit that automatically fine-tunes circulators based on thermal feedback from the cooling circuit.
