QSF-06 HF Preselector

Switchable Preselector Filter Board for FDM-DUO with active switch and band select output.

QSF-06 is a switchable preselector that allows the selection between 6 configurable filters. User can configure the internal board by choosing the right set of filters within the filter module family provided by ELAD or self-build. The QSF-06 board has also an on board active switch which ensure fast commutation time between transmission and reception state and a band select output to drive an external amplifier. Using the ELAD FDM-SW2 SDR software it is possible to configure the FDM-DUO to automatically select the proper filter as a function of the tuning frequency.

QSF-06 includes a bypass but does not include any filters.
