Although poorly attended, the recent IEEE Microwave Theory & Techniques Symposium (MTT-S) and exhibition featured several new products of note, especially in the measurement area. Anritsu, for example, launched their model MS2781A Signature High Performance Signal Analyzer, which examines a 30-MHz-wide instantaneous bandwidth from 100 MHz to 8 GHz (see Microwaves & RF, May 2004, p. 122). With frequency- and time-domain analysis capabilities, this instrument is ideal for determining the signal quality of a wide range of modulated carriers, including CDMA, QAM, and PSK signals. Not to be outdone, Agilent Technologies debuted their model E5052A Signal Source Analyzer, an all-in-one oscillator and synthesizer tester capable of evaluating sources from 10 MHz to 7 GHz. With a phase-noise floor of -178 dBc/Hz, this one-box instrument rivals the performance of dedicated phase-noise test systems for noise measurements at offsets from 1 Hz to 40 MHz. A potential customer for the instrument, Synergy Microwave Corp., introduced a new line of wideband voltage-controlled oscillators (VCOs), with total tuning range of 350 to 4200 MHz (see Microwaves & RF, June, p. 98). With generous output power and low phase noise, each VCO covers a number of different application frequencies, allowing designers to serve multiple end products with a single source. And for portable use, Rohde & Schwarz showed their model FSH6 handheld spectrum analyzer with a frequency range of 100 kHz to 6 GHz and noise level of -135 dBm for a 100-Hz resolution bandwidth. In addition, CAP Wireless impressed visitors with their CPA0220P broadband amplifier, with 15-dB gain and 10-W output power from 2 to 20 GHz while Analog Devices opened up a new product category with their model ADL5390, the industry's first two-channel vector multiplier designed to replace six discrete components for gain and phase control in wireless radio front ends.
