Balalem A., Menzel W., Macháč J., Omar A.: A simple ultra-wideband suspended stripline bandpass filter with very wide stop-band, IEEE Microwave and Wireless Components Letters, Vol. 18, No. 3, pp. 170-172, March 2008.
This letter introduces a simple ultra-wideband suspended stripline filter with a pass-band from 3.1 to 10.6 GHz and a very wide stop-band up to more than 25 GHz. The filter is realized by capacitive coupling of a quasi-lumped low-pass filter to the I/O ports. Insertion loss in the pass-band is better than 0.5 dB. The filter has a length of 13.8 mm. Excellent agreement is achieved between measured and simulated results.
