Digilogic’s RF UP/Down Converter for VST has been designed with latest cutting edge technology which is compatible with National Instruments hardwares / products. To extend the frequency range of operation of Vector Signal Transceiver (VST), we can use this up/down converter with VST. It will up-convert the IF signal of VST either to X or Ku band and down-convert X or Ku band input signal to IF frequency level acceptable for Vector Signal Transceiver.
We can also share 10 MHz clock between this up/down converter and VST. We have two bandwidth options available one with 200 MHz and another with 1 GHz. It also comes with a programmable attenuator on the output path providing upto 100 dB of attenuation in 0.5 dB steps.
Applications:
- EW Systems
- Radar Systems
- Simulators
- Communication Systems
Features:
- Wideband RF input, 8 to 12 GHz or 12 to 18 GHz
- 1 GHz Instantaneous Bandwidth
- One Channel of RF Upconversion
- One Channel of RF Downconversion
- Standard 2U 19-inch Rack Mount
