The THOR Series from EM Research are Programmable Frequency Synthesizers that operate from 1 to 18 GHz. The synthesizers provide an output power of up to 14 dBm and require an external reference from 5 to 200 MHz. The synthesized signal has a low phase noise with harmonics less than -25 dBc and spurious less than -60 dBc. The synthezisers require a supply voltage of 5, 8 or 15 VDC and draw a current of under 300 mA. They are available in a module that measures 2.5 x 1.1 x 0.4 inches with SMA connectors.
