Can be used to improve dynamic range of a (reflectometry) measurement by removing out of band noise.
Tunable sections (max 4) with different bands allow zooming in around several resonator frequencies. Build-in buffer amplifiers compensate for the filter losses. Bands can be designed anywhere between 60MHz and 1.5GHz with a tuning range of at least 1:2
The tuning is voltage controlled so future versions could be designed with remote tuning (SPI-rack)
several versions can be build:
