Broadband Microwave Tuner Delivers High-Speed Switching

Forming a complete 500-MHz to 18-GHz down-conversion system, the Echotek series RF 1800GT VME-bus microwave tuner targets signal intelligence, radar, and electronic-warfare applications. The modules reportedly set new benchmarks for low phase noise, fast switching speed, and high dynamic range. The tuner features a direct digital synthesizer, which uncouples tuning speed from phase noise, and consists of two single-slot VME modules: the 1800RF radio frequency and 1800S synthesizer modules. Simultaneous analog outputs of 80 MHz and 500 MHz are centered at 160 MHz and 1 GHz, respectively. The analog outputs are suitable for direct input into an external a/d converter for special signal processing, spectral analysis, and pulse parameterization.
