The SC5306A from Signalcore is a three-stage super-hetrodyne down-convertor with integrated local oscillators (LO) that delivers excellent image rejection over single stage conversion. It has an RF input frequency range from 1 MHz to 3.9 GHz, a low phase noise of -108 dBc/Hz at 10 kHz offset, a noise floor of -150 dBm/Hz, signal bandwidth of 20 MHz and measurement sensitivity of -164 dBm/Hz. It has been designed for demanding applications such as cable modem testing, software defined radio development and spectral monitoring, and as a sub-system component in a spectrum analyzers. The down-converters are available in three form factors - USB, PXI Express, and a core module with the SPI/USB/RS-232 communication interface.
