Ansoft Corporation recently acquired Compact Software. This new development offers a win-win relationship among Ansoft, Compact, and — most important — the microwave/wireless circuit design industry. Ansoft wins advanced linear and nonlinear circuit simulation; Compact wins enabling electromagnetic (EM) simulation technology; and the microwave industry wins a clear, viable and comprehensive sol...

A four-device broadband solid-state power amplifier, which is based on radial waveguide power-dividing/combining circuit, has been investigated in this work. The fabricated power amplifier combining four monolithic microwave integrated circuit power amplifiers shows a 12–16.6 dB small-signal gain over a broadband from 6 to 14 GHz. The measured maximum output power at 1 dB compression is 25.6 dB...

This paper features a radical and highly accurate method of designing a microwave amplifier. A Full-wave Electromagnetic Simulator, which is based on the Methodof-Moments (MoM) numerical method, is used in parallel with the conventional microwave circuit simulator to demonstrate a superior performance outcome such as Stability, Return Loss and Small Signal Gain. This method known as EM/Circuit ...

This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its bes...

A modified genetic algorithm is presented for parameter extraction of small signal equivalent of microwave power GaAs MESFET. A new approach of genetic algorithm-based model in the paper is applied to determine the equivalent circuit elements of GaAs MESFET directly from measured S-parameters biased in the active region. The results of calculation show that the method presented is suitable for ...

Abstract: The analysis of transversal filters based on a novel cell design in common-source configuration (TF-CS) is presented. Based on this approach, a distributed transversal filter was designed as a monolithic microwave integrated circuit (MMIC) for optical-CDMA receiver systems [1]. In order to assess its performance, a transversal filter based on Gilbert cells (TF-GC) was designed using t...

Microwave circuits embedded in a multi-layer resin PCB are demonstrated using low loss resin materials. Resin materials for microwave frequencies were compared with conventional FR-4 with respect to dielectric and conductor loss factors, which proved that losses could be reduced drastically with the low loss material and design optimizations. Baluns, switches and BPFs were designed and fabricat...
