“…Capacitive tuning with an inductive inverter can be used to reduce the return loss for the entire tuning range [18,19]. Simultaneous tuning of both capacitance and inductance with stub can also be used to reduce return loss and insertion loss for the entire operating range of the filter [20]. The filter roll-off is not very sharp, however can be improved by the use of a high-impedance transmission line and a higher order of the filter.…”

Abstract-In this paper we present the design and fabrication of an RF MEMS tunable band-pass filter. The band-pass filter design uses both distributed transmission lines and RF MEMS capacitances together to replace the lumped elements. The use of RF MEMS variable capacitances gives the flexibility of tuning both the centre frequency and the band-width of the band-pass filter. A prototype of the tunable band-pass filter is realized using parallel plate capacitances. The variable shunt and series capacitances are formed by a combination of parallel plate RF MEMS shunt bridges and series cantilevers. The filter operates at C-X band. The measurement results agree well with the simulation results.

“…Устройства на основе микро-полосковых линий нашли широкое применение в электронике из-за низкой стоимо-сти производства и миниатюрных размеров. Наиболее распространеными методами пере-стройки резонансной частоты микрополоскових резонаторов являются использование варкторов [1], p-i-n-диодов [2], микроелектромеханических систем (МЕМС) [3,4]. МЕМС, в отличии от варак-торов и p-i-n-диодов, обеспечивают больший диапазон перестройки частоты и плавное изме-нение во всем диапазоне.…”

“…Hence, MEMS schemes have attracted much attention, which present a very promising scheme in realizing a wide range of RF and microwave tunable components and devices. In the literature, many types of tunable devices based on MEMS technology can be found, including phase shifters [20,21], antennas [22] and filters [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]. In this paper, a short overview regarding the current status of MEMS based tunable filters is presented.…”

“…MEMS switches are also used in realizing tunable filters that are of lumped element and periodic structure types. In [28], a commercially available MEMS switch was used to realize tunable highpass and low-pass filters. The designed filters cover the frequency tuning range over 6-15 GHz.…”

Abstract-An overview of state-of-the-art frequency tunable technologies in the realization of tunable radio frequency (RF) and microwave tunable circuits is presented with focus on filter designs. Those enabling techniques and materials include semiconductors, microelectro-mechanical systems (MEMS), ferroelectric and ferromagnetic materials. Various performance indicators of one-dimensional tunable filters are addressed in terms of tunability, losses, signal integrity and other aspects. Fundamental limitations of the classical one-dimensional tuning method are discussed, which makes use of only one type of tunable elements such as either electric or magnetic tuning/controlling of circuit parameters. Requirements of simultaneous electric and magnetic two-dimensional tuning techniques are highlighted for achieving an unprecedented and advantageous wider modal tuning. It is believed that this emerging scheme will lead its way in the realization of future highly efficient and tunable RF and microwave components and devices.
