Abstract
This paper describes a new type of broad- band band-pass filter in which both the center frequency and band width are vari- able. The filter is composed of four bal- anced mixers, two loca loscillators, an amplifier, and high-pass and low-pass fil- ters. The center frequency and band width can be varied by changing the frequencies of two local oscillators. The center fre- quency is variable in the range 2-16 GHz, and the band width in the range 20-800MHz.
