AbstractIn this paper we discuss the performance of a proof-of-concept of a tunable band pass filter (BPF)/Low Noise Amplifier (LNA) hybrid circuit for a possible gain-compensated down-converter targeted for the next generation of K-band satellite communication systems. Electrical tunability of the filter is obtained through the nonlinear electric field dependence of the relative dielectric constant of a ferroelectric thin-film such as strontium titanate (SrTiO3) or barium strontium titanate (BaxSr1−xTiO3). Experimental results show that the BPFs are tunable by more than 5%, with a bipolar biasing scheme employed. The BPF/LNA tunable hybrid circuit was used to study the effect of tuning on the hybrid circuit's performance especially on the amplifier's noise-figure and the gain.

In this paper, a dual band microstrip bandpass filter has been proposed utilizing three edge coupled resonators, interdigital stubs and DGS technique. To enhance the coupling degree, two interdigital coupled feed lines are employed in this filter. The suppressing cell consists of stepped impedance ladder type resonators, which provides a wide stopband. The proposed suppressing cell has clear advantages like low insertion loss in the passband and suitable roll off. The frequency response of the filter looks like a standard dual band band-pass filter. The filter exhibits a dual passband with resonant frequencies at 2.2GHz and 3.45GHz covers LTE1 and LTE22 bands.
