Abstract:
A bandpass filter for a wide frequency band such as UWB is disclosed. The bandpass filter can receive a pair of signals, namely a differential signal, and output a single signal, namely an unbalanced signal. A transmission characteristic of the bandpass filter having an attenuation pole near both sides of the passband can be achieved.
