Abstract :
The authors describe a six-pole, 12-GHz, pseudoelliptic 76-MHz bandpass filter which achieves a stopband attenuation of greater than 50 dB up to 25 GHz. This design eliminates the need for a separate low-pass filter in applications such as output multiplexers of satellite transponders. Equivalent loss performance can be achieved for substantial savings in mass and volume.<>
