650-W CW dual notch filter

April 09, 2018 // By Jean-Pierre Joosting
High-power dual notch (reject) filters manufactured by RLC Electronics are designed using interdigital finger structure on planar configuration. This interdigital finger resonator provides ultra-wide band with two notches throughout the passband.

The unit in the picture above operates over the 500 to 2500 MHz band with two notches mid-band, and handles 650-W CW.  The filters exhibit low loss (<0.4 dB in the passband) and good VSWR (<1.25:1) and are designed to operate over severe military environments.
