A high-performance 6-18 GHz dual-channel MMIC (monolithic microwave integrated circuit) T/R (transmit/receive) module with significant advances in integration and performance is presented. This advanced module features critical spacing for 2D arrays, an aluminum silicon carbide housing, multilayer ceramic substrates for RF and control circuitry, a custom hermetic DC multipin connector, high-performance MMIC LNAs (low-noise amplifiers) and power amplifiers, and specialized multifunction MMIC chips for a reduced parts count. Each of the two channels feature a selectable horizontal and vertical polarization capability. The module is very densely packaged with two complete T/R channels occupying 0.97 in/sup 3/.<>

The authors present a comprehensive approach to predictable yield optimization. They utilize a new physics-based statistical GaAs MESFET model which combines the advantages of the DC Khatibzadeh and Trew model and the small-signal Ladbrooke formulas. The yield of a broadband amplifier was significantly improved after optimization. Predicted yield over a range of specifications was verified by device data. The benefits of simultaneous circuit-device yield optimization assisted by yield sensitivity analysis are demonstrated.<>

The authors describe the design and performance of a miniaturized 35-GHz power amplifier. The two-stage amplifier has achieved an output power of 1 W with an associated gain of 10 dB and a power-added efficiency of 25.1%. The design is based on a TRW 0.25- mu m T-gate pseudomorphic InGaAs high electron mobility transistor (HEMT) device technology. The amplifier was designed using a 1-mm device driving a 2-mm device. The complete amplifier mounted on a carrier is 0.26 in*0.16 in*0.02 in. The amplifier results reported here represent the best power gain and efficiency performances achieved from a single amplifier at 35 GHz.<>

An approximate analytical model for the CPW (coplanar waveguide) step discontinuity is presented which includes a lumped shunt capacitance as the dominant effect. Good agreement is obtained with data from extensive 3-D field simulations, and verified by a limited number of measurements on alumina. The magnitude of the discontinuity is found to be smaller than indicated in previous work, but it is nevertheless of the same order as a microstrip step in a comparable situation. These effects need to be taken into account in any serious design, and the model presented, when incorporated into CAD (computer-aided design) circuit analysis programs, will allow rapid evaluation of performance.<>

A complete calibration procedure for a fast sampling oscilloscope has been developed. This calibration makes it possible to use time-domain-reflected, time-domain-transmitted (TDR-TDT) systems at a quantitative level as a time-domain network analysis (TDNA) system. The data acquisition and calibration programs are implemented on a personal computer. All measurements are achieved in the time domain; the errors are corrected in the frequency domain, after Fourier transform. The bandwidth of the system extends from DC to 20 GHz. A whole calibration is achieved in a time comparable to LRL calibration on a classical network analyzer.<>

A double balanced diode mixer with all circuitry contained on a single MMIC (monolithic microwave integrated circuit) die has been designed and fabricated. The mixer consists of four diodes arranged in a star configuration connected to several balun-type structures. The configuration allows extracting the IF (intermediate frequency) signal at a node which is a virtual ground to both LO (local oscillator) and RF signals. Thus, compared to conventional MMIC mixers, a significant improvement in extracting the IF signal to achieve a broad bandwidth performance is possible. On-chip matching circuitry is included between diodes and baluns to enhance performance across a 6-GHz IF bandwidth.<>

A three-dimensional full-wave analysis of tapered microstrip lines is carried out in the time domain. The method used is the conformal-grid FD-TD (finite-difference-time-domain) method. Computed results are compared with experimental ones and those obtained by the finite-element method. The results agree well. As a result, it is shown that the propagation characteristics are very different from those obtained through two-dimensional modeling.<>

Three different circuit topologies of predistortion linearizers are proposed using MESFETs biased at low drain bias. The design of a C-band linearizer using two 1- mu -gate-length devices is detailed, and the achieved results compare favorably with conventional designs which use Schottky diodes. The linearizer reduced by 10 dB the intermodulation products of a 10-W power amplifier operating at 6 GHz, and up to 4-dB back-off.<>

Microwave and millimeter-wave signals can be generated using mode-locked semiconductor lasers with the intra-waveguide saturable absorbers. Monolithic and external cavity devices optimized for electrical and optical signal generation are discussed along with measurements of amplitude noise, phase noise, output power, and repetition rate tunability.<>
