Variable band-pass Filter

RTT-FIL - HFE High Frequency Engineering Sagl

The RTT-FIL series of programmable pass-band filters offer wide frequency ranges (five models covering 0.5-50 GHz), combined with excellent selectivity and stability. The filters are YIG-based, and excellent repeatability is achieved using state-of-the-art YIG current control circuit and internal calibration. The RTT-FIL series has been conceived for laboratory application such semiconductor testing, receivers preselection, and where a reliable microwave band-pass filter is required.
