LTC1562-2The LTC1562 and LTC1562-2, which are compact, high performance, "universal" continuous-time filter products, each containing four 2nd order Operational Filter blocks, are described.doi:10.1016/B978-0-12-800001-4.00473-7Max W. HauserAnalog Circuit Design...
Highpass filter = passband frequency range from 1.4 to 44.1 kHz with ripple of 0.02 dB and stopband edge at 600 Hz with an attenuation of 50 dB In the design of this crossover system, one possibility is to use an FIR filter, since it provides a linear phase for the audio system. Howe...

Rectangular waveguide stepped-impedance resonators (SIRs) are analyzed and employed in the design of an X-band filter with center frequency f 0 = 10 GHz and a bandwidth of 100 MHz. An attenuation of 80 dB is held up to 23.1 GHz and, compared to standard uniform-impedance-resonator filters...
For the outband spurious respond suppression, its upper stopband attenuation loss is lower than 20 dB from 2.6 GHz to 10 GHz, without affecting the center frequency and insertion loss. Good agreement between simulated and measured results. 展开 ...
The central frequency of the filter is 20 GHz, and the first spurious appears at about 40 GHz, which is two times the central frequency. In addition, the measured stopband attenuation of the filter is better than 50 dB from 21.24 to 37.71 GHz. 展开 ...
This filter has 3 dB cutoff frequency at 1.54 GHz. The transition band is only 0.26 GHz from 1.54 GHz to 1.8 GHz with corresponding attenuation levels of -3 dB and -20 dB respectively. Maximum insertion loss is 0.1 dB in the passband, and the stopband bandwidth with the attenuation level...
