Title :
Microstrip Variable Band-pass Filters Using Varactor-Diodes
Abstract :
Two microstrip variable band-pass filters for 6 GHz and 4 GHz bands are proposed and tested. The pass-band width varies from 310 MHz to 1.24 GHz for the varactor-diode coupled filter, and it varies from 380 MHz to 2.18 GHz for the filter which is composed of low-pass and high-pass filters connected in series. The center frequency of the both filters can be changed arbitrarily.
