Abstract

This disclosure relates to a devices and methods related to satellite information broadcasting. Example embodiments may include frequency shifting an intermediate frequency (IF) signal down-conversion from the microwave-band. As an example, down-conversion involving local oscillators may lead to frequency drift due to varying temperature and/or humidity conditions. Correcting for the frequency drift may provide an opportunity to remove or filter excess bandwidth. Further embodiments may include receiving, in a tuning request, information about a transponder type. A frequency translation module may be adjusted based, at least in part, on the transponder type related to the IF signal being input into the frequency translation module. Such frequency-shifting and transponder-specific filtering may allow Single-Wire Multiswitch (SWM) devices to provide output signals with narrower bandwidth, which may improve signal quality, cable run length, reduce power demands, etc.
