Abstract A reconfigurable tri/quad-band resonator and the application to band-pass filter have been demonstrated. By changing switching state of PIN diodes, can work in tri-band mode or quad-band mode. Correspondingly, resonant frequencies are 1.21 GHz, 2.0 3.23 1.27 2.61 3.41 respectively. Especially, has a combined structure lumped capacitors some transmission lines achieves small mechanical ...

A new resistorless single-input-multi-output (SIMO) universal transadmittance (TA) type filter employing two voltage differencing transconductance amplifiers (VDTA) and two grounded capacitors is proposed. The proposed topology realizes simultaneously low pass (LP), high pass (HP), and band pass (BP) filter functions. Band rejects (BR) and all pass (AP) filters are also realizable through appro...

In this paper, we develop a novel and effective algorithm for the construction of perfect reconstruction filter banks (PRFBs) with linear phase. In the algorithm, the key step is the symmetric Laurent polynomial matrix extension (SLPME). There are two typical problems in the construction: (1) For a given symmetric finite low-pass filter a with the polyphase, to construct a PRFBs with linear pha...
