The JAMPRO 20 KW FM Bandpass Filter (RCBC-X2X-FM) Iris Coupled Combline Band-pass Filter design provides superior performance. This is for medium/high power transmitter systems in a modular configuration. In addition, filter designs will include 2, 3, 4 or 5 sections. Assembly and testing will take place and shipping will be from stock.
Most of all, almost any value of rejection bandwidth can be provided. Achieved by the selection of a number of sections and coupling iris dimensions. Pass-band insertion loss minimizes with 18” high-Q aluminum cavities. Temperature stability remains maintained with use of invar tuning rods on copper center conductors.
Also, 1-5/8” or 3-1/8” connectors will be unflanged. Flanged connectors are available upon request. This design allows input power levels of up to 20 KW – with heat sinks.
