This paper describes the development of a low loss, high power, microwave switch MMIC design. The operating bandwidth of the switch was 7 to 11GHz. Simulated performance shows an insertion loss of 0.71dB at mid-band rising to 0.85dB at the band-edge. The estimated power handling capability of the switch is 6.3W at 1dB compression for 0/-10V control. Isolation is better than 27dB across the enti...

Radio Frequency Micro-Electro-Mechanical-Systems (RF MEMS) based switches are expected to play a key role in the field of microwave switching. Traits like low-loss performance; zero-power consumption and very low inter-modulation distortion have made these switches well suitable for high-performance microwave and millimeter-wave circuits. The design of RF MEMS switches, however, require sophist...

Introduction: Multi-throw switches are widely used in microwave circuits for switch matrices and true-time-delay phase shifting applications. Traditionally, the multi-throw switch uses GaAs MESFETs and pin diodes to perform its switching function. It exhibits good performances at low frequencies, but deteriorates in the high frequency range beyond 1 GHz [1]. On the other hand, the monolithic mi...

This paper is focused on the creation of an efficient electromagnetic model of MEMS switches which operates at microwave frequencies. The switches are first characterized using a full wave analysis based on a finite element method to extract the S-parameters of the switches for different geometrical dimensions. From the S-parameter database, a scalable lumped circuit model is extracted to allow...

The current state-of-the art of oscillator simulation techniques is presented. Candidate approaches for the next genertion of oscillator simulation techniques are reviewed. The method is presented which uses an efficient and robust convolution-based procedure to integrate frequency-domain modeling of a distributed linear network in transient simulation. The impulse response of the entire linear...

In recent years SIC has metamorphisized from an R&D based materials system to emerge as a key substrate technology for a significant fraction of the world production of green, blue and ultraviolet LEDs. Emerging markets for S i c homoepitaxy include high-power switching devices and microwave devices. Applications for heteroepitaxial GaN-based structures on S i c substrates include laserss and m...

We present the design and experimental results of an optically controlled high power pulse compression system. The rf parameters of the system are chosen to fit the requirements of the X-band Next Linear Collider design at SLAC. The system is based on the switched resonant delay line theory [1]. The high power microwave switch, required for this system, is realized using optical excitation of a...
