“…Little research of monolithic integrated design of S-band switched filter bank based on LTCC technology has been reported. So firstly the design in this paper is compared with the the designs of tunable filters using different methods in [4][5][6][7]. The design in this paper offers more channels for selecting than the three-channel switched filter bank based on MEMS technology, but the size of MEMS design is the advantage that LTCC cannot achieve.…”

“…In 2005, Reines et al developed a switched Ku-band filter bank using two single-pole triple-throw (SP3T) microelectromechanical systems (MEMS) switching networks and three end-coupled bandpass filters, and a tuning range of 17.7% from 14.9 to 17.8 GHz was achieved with a fractional bandwidth of 7.7 ± 2.9% and insertion loss ranging from 1.7 to 2.0 dB [4]. In 2011, Schulte et al changed filter microstrip size by means of Microelectromechanical Systems (MEMS) switches, and a filter with optional frequency was proposed with a center frequency of 630 MHz and a tunable frequency range of 537 MHz-728 MHz, and insertion loss between 2.5 dB and 5.5 dB [5].…”

Abstract-A S-band monolithic integrated switched filter bank has been designed to realize tunable working center frequency, and a tuning range of 12.9% from 2.7 to 3.05 GHz was achieved with interval of 50 MHz. The switched filter bank is designed using 8 eighth-order step impedance resonators (SIR) band-pass filters arranged in parallel rows. Microelectromechanical Systems (MEMS) switched circuit is integrated above filters for monolithic design combined with low temperature co-fired ceramic (LTCC) technology. The SIR bandpass filters are designed to resist Electromagnetic Interference (EMI) between components and introduce cross coupling to bring two transmission zeros and better out-ofband rejection. The monolithic integrated switched filter bank is only 74 mm × 24 mm × 2.5 mm, which realizes the monolithic integration of the device and enhances the reliability. The measured results show that the insertion loss and out-of-band rejection are in good working condition.

“…Electronically reconfigurable tunable filters are attracting more interests for research and development due to their increasing importance in wideband radar, multiband systems and electronic warfare systems [4]. In general, based on various tuning elements used, tunable filters may be classified as semiconductor (varactor diode and P-I-N diode) tunable filters [5][6][7][8][9], piezoelectric transducer (PET) tunable filters [10][11][12][13][14], RF microelectromechanical systems (MEMS) tunable filters [15][16][17], and ferroelectric materials tunable filters [18][19][20]. A well-known problem for tunable filters is the variation of the bandwidth as the centre frequency is tuned.…”

In the past few years, several satisfying various objectives and designs of reconfigurable integrated microwave filter and antenna have been proposed for wireless communication systems. Several designs are new concepts and techniques, whereas others are inspired from previous works. The improvement concepts of these designs can be reviewed from this compilation of studies. This paper begins with an explanation of the reconfigurable filter, reconfigurable antenna and reconfigurable integrated microwave filter and antenna, followed by discussion on several designs in terms of size, measurement, performance and technology used. Among various designs, reconfigurable on planar structures are extensively used because of their simple design procedures and easy to tune on the desired frequency, bandwidth and attenuation. Most of the existing studies are focusing tunable on single element, i.e. either on filter or antenna side; however, it limits the tunable range and flexibility of the filtering antenna response. An alternative design of filtering antenna can be suggested to produce reconfigurable tuning capabilities on both microwave filter and antenna to produce overall good performance for multifunction operation in RF/microwave applications.

“…An example is reported in [3] where the switching speed (� 80 /!s) is limited by the adoption of MEMS switches and a modest Q-factor is obtained (228). In [4]- [5] switched filter banks (SFBs) based on edge-coupled filters and MMIC switches with considerable insertion loss (�lldB) were presented.…”

The design of a 4-channel switched filter bank in the S-, C-band using PIN diode switches is described. Narrow band (3.2-3.5%) filters are designed on suspended substrate stripline. The biasing circuit allows the switches to be driven with TTL-compatible voltages and minimum biasing current. The average insertion loss measured was 3.6 dB corresponding to a Q factor of 580. Spurious responses were suppressed from DC to roughly 19 GHz.
