CPCI_SFXX0838M Frequcency Converter System

Sinolink CPCI_SFXX0838M Frequency Converter System is the combination of all the CPXI structured frequency converters from our company. It has a RF signal of 8-18 & 33-38GHz with a frequency stepping size of 10Hz. The downconverter IF frequency is either 400MHz or 1.2GHz, the signal bandwidth can be both 500MHz or 200Mhz, the upconverter IF frequency is set to be 400MHz, and the signal bandwidth is either 500MHz or 2000MHz. This frequency converter has a standard CPXI structure which makes it easy to form a multi-channel retractable system. The frequency converter also includes a CPXI chassis, a set of main control board, a set of frequency source modules, an IF up-conversion module, a RF up-conversion module, an output power amplification module, a RF down-conversion module and an IF down-conversion module in which all the frequency converters are in two-way and sharing a local oscillator.
The system’s up and down frequency converters are both designed to have individual dual-channels, the 2 channels share a local oscillator. The up frequency converter can produce pulse modulation signal with a pulse front ≤ 10nS; The down frequency converter can receive and process the pulse modulation signal in real time, the delay does not exceed 100nS. The system and the baseband processing module together constitute the radar simulation equipment which can generate radar parameters required for the target echo signal, clutter, interference signal, the scene signal.
