The microstrip T-resonator is a well established tool for determining broadband electrical properties of microwave materials, namely effective dielectric constant and attenuation. In this paper finite ground coplanar waveguide (CPW) T-resonators on high resistivity silicon are presented and evaluated. The multi-moding seen in CPW T-junctions is effectively eliminated through the use of gold wire bonds. The calibration independence of the CPW T-resonator technique is demonstrated and the predicted impedance independence of the CPW ¿T¿ is experimentally validated. The electrical property results obtained using the T-resonator on high resistivity silicon substrates are in good agreement with data from other characterization techniques. The CPW T-resonator is thus shown to provide rapid and accurate characterization of integrated microwave substrates.

A method for measuring S-parameters of a circuit embedded in a planar circuit environment is presented. The method utilizes an inductive and a capacitive probe. Experimental results are presented for probe measurements of reflection coefficient from 0.7 to 20 GHz with good agreement to verifying measurements up to 14 GHz. The method shows great promise for in-circuit S-parameter testing that has previously required physical modification or even complete disassembly to test sub-circuits in a microstrip environment.

Some load-pull test benches are developed at present time in different university laboratories. These characterization benches offer high capabilities and are well suited for the research activities. This paper presents the evolutions to apply the load-pull characterization technique issued from the research to the industrial world. This application involves choices to make. These ones are justified and detailed after descriptions of a research and an industrial load-pull characterization bench.

In this paper we describe a measurement technique to identify a nonlinear system in the presence of nonlinear source pull. Models identified with CW measurement data are not generalisable when nonlinear source pull is present. This is demonstrated on measured data and compared with the performance of the proposed technique. The method is based on two tone signals with very close frequencies that excite the system at the fundamental and harmonic frequencies. By varying the phase relation between the beat components, the system¿s nonlinear behaviour is separated from the nonlinear source pull. Note that such excitations can be generated using commercially available synthesizers with SSB IQ modulation options.

This paper describes a time domain measurement technique of large-signal RF pulsed waveforms, based on Agilent Nonlinear Network Measurement System (NNMS). A transistor is biased under pulsed conditions and the RF is applied during bias pulses. The paper shows how the time domain RF measurements are acquired during the pulses. Up to 12 harmonic frequencies are taken into account, in order to provide an accurate time domain voltage and current description at both transistor terminals.

A measurement based model for a microwave system operating in a power range up to several dB¿s of compression over its full operation frequency band is proposed. The model uses a limited amount of parameters, is easy to implement in an existing simulator, does not require the publishing of internal schematics, and predicts the response of the component over its whole working area. This model is hence a candidate for inclusion in data sheets.

This paper presents a measurement methodology to characterize the non-linear behavior of HFC (Hybrid Fiber Coax) return path components and sub-systems. The measurement method, based on NPR (Noise Power Ratio), takes into account the spectral and statistical nature of return path signals, those being different from downstream signals. The paper describes a reliable measurement set-up based on a filtered white noise source and a spectrum analyzer. Correction figures to apply to spectrum analyzer measurements, experimental best practices and measurement uncertainty are developed. The automation of the set-up is presented as well as some results concerning an electric return path amplifier and an optical return path system. The temperature behavior of those devices is compared by the way of the NPR. Also, a theoretical analysis of the relationship between tones distortions characterization and the NPR method is established and experimentally demonstrated. Therefrom, an alternative measurement method for return path systems is proposed to the attention of laboratories which do not possess NPR measurement capabilities.

Based on a previously established theoretical work, it first identifies the main limitations of noise power ratio figure of merit. Then, an appropriate alternative is proposed, along with its required measurement set-up.

This paper deals with the de-embedding problem of devices mounted in test fixtures. An original matrix approach for the de-embedding of the scattering parameters of the device under test (DUT) is presented. The implementation of this new de-embedding method uses a non-reflecting line (L), a reflect (R), and a match (M) as standards. The main feature of the proposed method is that the wave propagation constant is not needed in the de-embedding process. Because no redundancy is involved in the computations, this method is faster than the de-embedding method implemented with LLRM (Line-Line, Reflect, Match) and LRL(m)[2].
