Elliptic Function Highpass Filter

5 2-13 GHz Elliptic Highpass Filter Integrated Microwave Corp. offers a high-frequency true elliptic function highpass filter. This small-profile filter offers a nominal passband insertion loss of 0.7 dBa at 5.2 to 13 GHz. This superior rejection provides 20 dB at 4.9 GHz, and -40 dB nominal DC to 4.8 GHz, with a 3 dB cutoff at 5.15 GHz. Performance is comparable to a suspended substrate, but at one-quarter the size and cost.
