SIDC-6000 Series Microwave

Elcom’s SIDC-6000 is a high dynamic range microwave downconverter/tuner covering 0.5 to 26.5 GHz with 10 Hz tuning resolution. The SIDC-6000 provides essentially all of the RF functions of Elcom’s SIR-4000 receiver, excluding digital IF signal processing. The agile LO in this downconverter employs Elcom’s advanced frequency synthesizer architecture which combines a direct digital synthesizer (DDS) within a VCO-based PLL synthesizer. This combination delivers low phase noise, low spurious, and fast tuning speed along with the 10 MHz tuning frequency step size. The system provides scan and sweep frequency control modes.

There are two IF outputs: one centered at 1.2 GHz with fixed 500 MHz bandwidth, and one centered at 70 MHz with selectable IF bandwidths of 10, 20, 30 and 40 MHz. The 70 MHz IF has Automatic Gain Control (AGC) with fast attack time and programmable decay time, and the AGC power level is programmable. For operation under manual gain control, programmable attenuators on both IF channels provide 42 dB control range in 1 dB steps. Non-inverting or inverting spectral conversion can be selected independently for the two IF outputs. An option is offered to allow phase coherent operation of multiple SIDC-6000 downconverters.

The SIDC-6000 is engineered to provide superior RF performance in terms of dynamic range, low phase noise, and fast tuning speed. This RF performance, along with numerous signal control and system control features, make the SIDC-6000 an excellent solution for a wide range of demanding microwave downconverter applications.
