K&L to Display High Power Ceramic Bank Reject Filter

May 31, 2007

K&L Microwave will feature model 4DRN40-422.75/X3-O/O, a high power ceramic bank reject filter, in booth 1100 at this year's MTT-S IMS show.


This filter offers power handling capabilities of 100 W CW. Its ultimate return is also 1.9 times center frequency, with a lower insertion loss.

This filter, which is also called a notch filter, rejects one band of frequencies, and passes higher and lower frequencies. The dimensions are 2.25” L x 1.66” W x 0.60” H—smaller than equivalent cavity filters (4.750” L x 1.13” W x 2.375” H) (both sizes exclude connectors).
