“…The microstrip line distribution parameter has simple, compact structure, and it is easy to integrate. Therefore, this design chooses to use microstrip lines of different widths to respectively realize the capacitance and inductance of the filter circuit [6]. This design uses FR4 dielectric plate, and its plate parameters are as follows: plate thickness h=0.8mm, dielectric constant ε r =4.4, dielectric loss tangent Tan D=0.02.…”

In this paper, a tunable filter integrated SPDT switch based on PIN diode is proposed. The band-pass filter response is realized by using microstrip lines with different characteristic impedances, and the filter-integrated SPDT switch with tunable center frequency is designed by loading a varactor diode and PIN diodes. The measured results show that its filter response can be tuned in the range of 1.5 to 2.065 GHz, the insertion loss is 1.53-2.69 dB, and with well return loss and port isolation.
