A Miniature SPDT Switch for Hi-rel Space Applications Dow-Key Microwave Corp. Ventura, CA The trend toward component miniaturization is not new; it has already become prevalent in the commercial industry, especially in the wireless sector. However, the space industry is more conservative and, although there is good reason to...

A Low Cost, 1200 MHz Frequency Synthesizer Programmed Test Sources Inc. (PTS) Littleton, MA As wireless production expands, test systems requiring high performance LO sources are proliferating. To address the price pressures found in the wireless market, a new low cost synthesizer that features fast switching and low phase...

Dual-band GSM/PCS Handset Antennas Ace Antenna Co. Chatsworth, CA Today's new cellular telephone must be capable of operating in two distinct frequency bands to be compatible with the various operating systems it is likely to encounter. As a result, the unit's single-handset antenna must perform efficiently and effectively within...

A 2 kW Solid-state Pulse Amplifier Wavesat Te´le´com Inc. St-Laurent, Quebec, Canada The model WPA-129063-53PR solid-state power amplifier system is a stand-alone, 19" rack-mount unit capable of amplifying RF pulses to a level in excess of 2000 W peak power with five percent duty cycle (100 W average power)....

Testing of Smart Antenna Systems Smart antenna systems must be tested to verify the various claims made by the system designer and manufacturer. The tests should be performed primarily to evaluate the most and least successful functions of the system under consideration. Extensive testing should also establish the best...

Experimental Adaptive Nulling with a Genetic Algorithm An adaptive antenna system rejects interference by placing a null in its antenna pattern in the direction of the interfering source. A single-element antenna needs at least one other element or some scattering object to form a null. Thus, adaptive antennas are...
