“…As indicated in (9), the coupling coefficient is only decided by electric field energy of the overlapping region between coupled TLs when the operating frequency and the surrounding environment are determined. Electric field distribution analyses are proposed for two MS TLs, tunable SSPP TLs and packaged tunable SSPP TLs with the same distance, as shown in figures 5(a)-(d).…”

“…High integration, miniaturization, and reconfigurability are important development trends of modern communication and radar systems, which put forward higher requirements for the electromagnetic compatibility (EMC) and multi-functional performance of microwave circuits and systems [1][2][3][4][5][6][7][8][9]. One of the many solutions is to propose new kinds of transmission channels with both multi-functional ability and excellent EMC performance.…”

High integration of modern microwave circuits and systems puts forward higher requirements for multi-function and electromagnetic compatibility (EMC) performance of transmission channels. In this paper, we design a multi-functional spoof surface plasmon polariton (SSPP) channel which can realize continuous phase modulations more than 180° in X-band and continuous amplitude modulations from -1dB to -40dB in Ku-band. Based on the multi-functional SSPP channel, we propose two EMC technologies, including the substrate integrated packaging (SIP) method and the tunable wavenumber mismatching (TWM) method. The SIP method can effectively isolate the inside and outside of the package to avoid mutual interference with easy fabrication and compact size (0.13 λ0 × 0.043 λ0). Meanwhile, simulated and measured results demonstrate that the coupling coefficient of the packaged SSPP channels is about 8-10dB lower than that without packaging, and 13-15dB lower than that of traditional microstrip channels in the whole X-band and Ku-band. The TWM method is realized by designing the wavenumber difference between two channels. Simulated and measured results demonstrate that the coupling coefficient of two adjacent channels with a distance of 1/30 λ0 can be reduced to around -30dB in varied frequency bands. Therefore, the two proposed EMC technologies have application potentials of highly integrated microwave circuits and systems to achieve multiple functions and good EMC performance.

This paper proposes a low-noise receiver frontend for nanosatellite and Cubesat platforms. The frontend is composed by a Low-Noise Amplifier (LNA) and two Substrate Integrated Waveguide (SIW) filters, providing a frequency reconfigurability to the system. The two filters operate in the 13 and in the 14 GHz uplink bands, and are selected by means of a pair of solid-state SPDT switches. As a results, 15.5 dB gain with 2.4 dB noise figure for the 13 GHz configuration and 17.8 dB gain with 2.3 dB noise figure for the 14 GHz configuration are obtained. This work is important since demonstrates a low-cost solution for satellite radio apparatuses based on commercial components on a standard PCB.

In this paper, an analysis of open stub resonator is presented and its application in dual isolation band of Single Pole Double Throw (SPDT) switch is proposed. A mathematical model and the characteristic of the bandstop of the resonator were analyzed and discussed. The open stub resonator was implemented using the microstrip transmission line and able to switch between bandstop and allpass responses. Frequency bands of 2.3 and 3.5 GHz were chosen to demonstrate the dual isolation band in the switch design. The performance results of the SPDT switch showed that the isolation was greater than 30 dB, return loss was greater than 10 dB and insertion loss less than 2 dB at the center resonant frequency of 2.3 and 3.5 GHz. The potential application of the proposed dual isolation band of SPDT switch is for multi band RF front-end system such as WiMAX, LTE, WiFi and HyperLAN.
