Although the basic approach is derived from the desire to reach higher frequencies than those readily achieved by thinning bulk crystals, there have always been competing technologies for fundamental material or processing problems that have impeded the development. Finally, a point was reached in the wireless market wherein competing technologies appeared unable to meet the demands of modern wireless applications and thin film approaches began to receive some emphasis.

It provides return loss better than 18 dB from 100 MHz to 40 GHz. The main advantage of the design is that the DC blocking capacitor is placed directly on top of a wide grounding Si pedestal, thanks to M/A-COM's HMIC technology, reducing the ground inductance. At the RF side of the circuit, two 100-Ohm nichrome resistors have been put in parallel giving 50 Ohm. A small stub between the 100-Ohm resistors compensates for the inductance giving a very good match up to 40 GHz, Bond-wire pads have been designed on the chip and also on the host PCB to match the inductance of double wire-bond at the RF port.","PeriodicalId":177645,"journal":{"name":"Radio and Wireless Conference, 2003.

A novel set of design equations for a generalized N-stage Doherty amplifier is introduced. For the first time, this technique is applied to the design of a WCDMA power amplifier (PA). The designed PA meets WCDMA requirements, and exhibit a power-added efficiency (PAE) of 34.5% at 6 dB back-off and 16.9% at 12 dB back-off. These PAEs are 2 times and 4 times better, respectively, than that of a single stage linear PA at the same back-off levels. The PA is capable of delivering up to 28.6 dBm of output power, and has a maximum adjacent channel power leakage ratio of -38 dBc and -51 DBc at 5 and 10 MHz offset, respectively.

A. Abidi, December 1995]. A new Ka-band high-speed direct conversion wideband six-port receiver was designed for wireless communications. This QPSK six-port receiver operates using analog signal processing (ASP). The QPSK DCR consists of a receiver front-end, a QPSK demodulator and a carrier recovery module. A reverse modulation loop (RML) was used to provide a rapid carrier recovery. The maximum bit rate, around 120 MB/s, is limited by the speed of the base-band circuits. The new hardware receiver is proposed for use in wide Ka-band wireless mass-market QPSK communications such as LMDS services.

Satimo has developed a compact and cost-effective measurement platform, which is able to perform rapid 3D testing of the pattern radiated by wireless devices. The 3D radiation analyzer called StarProd is derived from the well-established Satimo spherical test facilities based on multi-sensors technology. This paper describes in detail the 3D radiation analyzer and its different configurations for power, spurious, vector and active measurements. The achieved measurement accuracies are also presented.
