A novel implementation of high frequency switch matrix is proposed in this paper. The solution is based on substrate integrated waveguide (SIW) in low-temperature cofired ceramic (LTCC) technology. The approach demonstrates significant beneficent of using SIW as a connection and cross transmission of the Switch matrix, offering high isolation and good transition performance in high frequency. A K band 4 4 switch matrix is simulated and fabricated, with good performance demonstrated experimentally.Index Terms -Switch matrix, Substrate integrated waveguide, LTCC.

“…Apart from the research reported in [3] and [4], most switch matrix papers investigate common approaches either based on Single-Pole-N-Throw (SPNT) switches [5] or crossbar switch matrices [6], [7]. In [5], a monolithic integration that offers minimum number of switches is reported. However, in comparison with crossbar, this design only operates with small bandwidth, limited RF performance and relatively larger matrix physical size.…”

A novel implementation of wideband large switch matrices is proposed in this letter. The solution is based on staircase geometry. The approach demonstrates significant reduction in the number of control signal required compared to all existing RF MEMS switch matrix geometries, while maintaining the performance. This letter presents the design and characteristics of a semi-T switch cell and a 3 3 staircase switch matrix. The measurement of the switch matrix demonstrated excellent RF performance of maximum insertion loss of 2 dB, a return loss of better than 15 dB and an isolation higher than 40 dB for frequencies up to 40 GHz. To our knowledge, this is the first RF MEMS staircase switch matrix ever reported.Index Terms-RF MEMS, RF MEMS switch, switch matrix.

“…1(a), the development of monolithic switch matrices involves design and optimization of the switches, interconnect network, and their integration. The authors have introduced a compact interconnect network that takes advantage of electromagnetically coupled vertical transitions and back side patterning in [5]. Here, the same concept is employed to construct a unique monolithic 3 x 3 switch matrix.…”

“…1 The switches are based on CPW ports and can be easily integrated with the interconnect network that employ CPW lines. Electromagnetically coupled vertical transitions have been used to transfer the signal to the backside on the required crossovers [5]. This switch matrix can be easily used as a basic building block to build larger matrices.…”

In this paper, for the first time, monolithic integration of an RF MEMS switch matrix is presented. Novel SP3T RF MEMS switches are designed and monolithically integrated with an electromagnetically coupled interconnect network. A thin film fabrication process exclusively for this purpose is developed and fine tuned. A prototype unit of a 3 x 3 monolithic switch matrix is fabricated and tested. The measured results show a good RF performance for the frequency range of 9.5GHz to 13.5GHz. The proposed monolithic 3 X 3 switch matrix can be easily expanded to a larger matrices using Clos networks.
