35 KW FM Bandpass Filter

35 KW FM Bandpass Filter

The Jampro 35 kW FM Bandpass Filter (RCBC-X3X-FM) is now available. Moreover, the Iris Coupled Combline Band Pass Filters design is for superior performance. In addition, these are for medium/high power transmitter systems in a modular configuration. Also, filter designs with two, three, four, or five sections are assembled, tested, and shipped from stock.

In addition, we can provide almost any value of rejection bandwidth. It requires proper selection of the number of sections and coupling iris dimensions. Moreover, 24” high-Q aluminum cavities minimize passband insertion loss. Also, invar tuning rods mounted on copper center conductors provide temperature stability.
