This paper presents guidelines for the design of dual-band transformers in both rectangular and ridge waveguide technologies. Four to eight transformer sections are used to satisfy specifications for advanced satellite and terrestrial communications in C-band and Ku-band. Compact designs are obtained by synthesis of wideband components, which are then optimized for dual-band application. Measurements of a Ku-band prototype verify the design approach

An eight stage distributed amplifier with 12.5 dB /spl plusmn/ 0.45 dB gain and 50 GHz bandwidth has been demonstrated in a commercially available 0.1 /spl mu/m metamorphic GaAs HEMT (MHEMT) technology. The amplifier has a minimum noise figure lower than 2.5 dB in the bandwidth. The group delay variation from 9 to 40 GHz is /spl plusmn/ 7.5 ps and circuit consumption is 0.4 W. Such amplifier has been packaged with a high responsivity photodiode into a fiber pig-tailed module. Eye diagrams measurements demonstrate the successful high-speed operation of the photoreceiver.

Hot carrier effects become an important consideration as device dimensions shrink to address higher frequency of operation. SiGe mixers have increasing importance due to potential for high level of integration and low cost. This session addresses the hot carrier effects in both GaAs and silicon circuits, 5 GHz mixer development, as well as tunable elements and isolation issues for insulating and silicon substrates.

This session comprises seven papers covering recent developments in ferrite phase shifters, lumped element circulators, left-handed ferrite waveguides, microwave inductors and magnetostatic wave (MSW) oscillators. The stress related insertion loss in longitudinal field ferrite devices is analyzed and a method is suggested for screening ferrite rod samples to determine suitability for use in dual-mode phase shifters. A duplexing reciprocal phase shifter is described that integrates a circulator function into the phase shifter structure. Two papers discuss improvements to lumped element isolator and circulator designs through improved techniques and a novel gyrator circuit. A lefthanded periodic, ferrite-filled waveguide structure was modeled and fabricated. Measurements confirmed the existence of pass-bands below the waveguide cut-off frequency. Ferromagnetic RF integrated inductors are described that exhibit a record breaking Q 12 at 1GHz using soft CoNbZr films and closed magnetic circuits. Finally a novel regenerative detector using a MSW resonator is discussed that combines high sensitivity with simplicity and potentially low cost..

This paper describes the first combined distributed amplifier/true-time-delay phase shifter. The design reduces the cost and size of broadband self-steering array systems. A proof-of-concept prototype is designed and fabricated using discrete components. The result is a measured gain of 9.5 ± 3 dB from 0.5 to 3.5 GHz with a maximum phase shift of 35° at 3.5 GHz.

A novel CMOS subharmonic mixing technique based on threshold voltage modulation with higher LO-to-RF isolation is presented in this paper. A 2.1GHz subharmonic mixer is designed using this technique in a 0.18µm standard digital CMOS process by applying the LO signals at the bulk terminal of PMOS transistors. The mixer has a measured conversion gain of 10.5dB, an IIP3 of −3.5dBm, and a noise figure of 17.7dB while consuming 2.5mW in each mixer core. This circuit architecture increases the second harmonic LO-to-RF isolation to above 67dB and hence can mitigate LO leakage issues in wireless receivers.
