Teledyne Microwave Solutions (TMS) has developed a family of YIG-based synthesizers that reduces the traditional high cost of a high quality, low phase noise, broadband frequency source. These modular YIG designs simply plug into a laptop or desktop using the USB connection to create a fully functional synthesizer, one that has superior performance to the industry standard architecture based on voltage-controlled oscillators (VCO).

Various models are available, operating in bands from 2 to 13 GHz. One design spans 6 to 13 GHz with 1 MHz step size. The output frequency is set with a simple “set frequency” command from the PC. At 6 GHz, the phase noise is ‐70 dBc/Hz at 100 Hz offset, ‐90 dBc/Hz at 1 kHz, ‐95 dBc/Hz at 10 kHz, ‐125 dBc/Hz at 100 kHz and ‐145 dBc/Hz at 1 MHz offset. Spurious signals are a maximum of ‐60 dBc, and harmonics are no greater than ‐20 dBc. The nominal output power is between +10 and +16 dBm. A 10 MHz frequency reference signal is required, nominally around +5 dBm. The synthesizer is powered with +12 V DC and draws a maximum of 600 mA. The operating temperature range is +10° to +50°C.

TMS synthesizers can be configured in a variety of shapes, sizes and frequencies to meet custom requirements. Serial interfaces are available, in addition to USB. By offering low phase noise YIG oscillator technology in a complete synthesizer, TMS offers a high performance integrated solution with a better ROI than other industry options.
