Broadband Synthesizer

The UFS series is an ultra-fast, ultra-low phase noise, high performance, broadband synthesizer, designed specifically for ATE applications. The UFS series is based on direct-analog design techniques combined with dds capability for fine freequency resolution. the series is ideally suited for Agile Radar, EW and RDC systems where low phase noise and fast switching speeds are of primary importance.

IBS Synthesizer

This three slot VME size, ultra high performance, broadband synthesizer is designed specifically for ATE application. The IBS series synthesizers are based on indirect PLL design technology with internal DDS for fine resolution. this sereies is ideally suited for ATE as well as radar and EW system applications where broadband coverage, low phase noise, fast switching speeds and reliability are of primary importance. The VCO/PLL design approach realizes much faster switching speeds, good microphonic performance and lower power consumption. This unique design architecture allows for switching speeds of 10 to 250 us, combined with low phase noise levels.

Clock Generator

This high frequency clock generator for SONET systems offers low jitter of 21.4GHz and is a phase-locked souce having high power differential sine wave outputs. The output power is +25 dBm per each line of the differential output. this device is intended for timing 150 to 200 MHz applications in 40 GBs SONNET systems. The unit operates from a complementary PECL external reference source such as a crystal oscillator. Phase noise of 21 GHz output is <-105 dBc/Hz at 100 kHz from the carrier and non-harmonic spurious are <-80dBc.

38GHz Synthesizers

A new series of dual-output synthsizers from elcom technologies has been designed for use in high capacity microwave and millimetre-wave radios operating at frequencies up to 38 GHz.

The LCDFS series of synthesizers freatures -108dBc/Hz phase noise as standard at 100kHz offset from 10GHz, with an optional improved specification to -118dBc/Hz, and guaranteed zero-phase-hits. This makes the synthesizer suitable for high-speed data transmissions at 16, 32, 128 and 256QAM.

The LCDFS series has a tuning bandwidth up to 1350MHz and step sizes ranging from 25kHz to 10MHz. Output power range is +12dBm to +18dBm and switching speed is less than 25ms.

Harmonic level for the synthesizers is specified as -20dBc, and stability is +-3ppm across the full operation tremperature range. DC power consumption is less than 4W, and operating temperature range is -35 to +70C. The device is packaged as standard in a 100x95x30.5mm3 housing, and other package styles are also available.
