Abstract :
This paper describes the design and fabrication of compact bandpass filters for UHF TV channels using Stepped Impedance Resonators (S.I.R.). The fabricated channel filter shows an insertion loss of below 3.0 dB with 6 MHz passband at a center frequency of 690 MHz. The center frequency can be changed ±50 MHz.
