SC2410 – 20 GHz 4-Channel Frequency Converter

The SC2410 is targeted at users looking for extremely flat group delay performance and phase synchronization across all channels. When combined with pre-distortion algorithms such as those implemented in National Instruments’ Vector Signal Transceivers, group delays of under 1 ps are attainable across any 1 GHz band in the 1 to 20 GHz frequency range. All up- and down-conversion paths share a common oscillator input, resulting in less than 2 degrees of phase variation across all 8 paths. The instrument is housed in a compact 1U rackmount enclosure.

Description

The SC2410 is a 4 channel 18 GHz Up/Down Converter comprised of eight mixers all sharing a common coherent LO signal. Passive, triple balanced mixers offer excellent spurious suppression with overlapping IF and RF bands. The frequency range for the LO and RF ports is 5-18 GHz while the IF port extends from 2 to 18 GHz.

Firmware control allows for the enabling and disabling of the common LO signal as well as providing access to a digital step attenuator that can be used to set the LO signal drive level at all eight mixers.
