“…In addition, because of high selectivity, low insertion loss, and very little dimensions, we used quasi‐elliptic bandpass filters based on SIR in our design, which was discussed in detail including design and application in [6] and [7]. The desired based‐on‐SIR filters are designed, simulated, and fabricated for three operating frequency in GSM.…”

In this article, a triplexer is presented for three operation frequencies in GSM, based on stepped impedance resonators (SIR).SIR structures have some characteristics, such as low weight, little dimension, and the ability of providing filter behavior with different frequencies in same dimensions. To design the triplexer, bandpass filters of each output should be design first. Parallel connection of three filters together causes an extreme increase in insertion loss of each filter and also reflection of power to the input. A novel based‐on‐SIR matching circuit is proposed to solve these problems. By connecting optimized matching circuits to three bandpass filters [1], which are simulated for three frequency ranges in GSM, the desired triplexer is obtained. This based‐on‐SIR triplexer is simulated and fabricated. The measurement results of the fabricated prototype shows a good agreement with simulation results. © 2010 Wiley Periodicals, Inc.
