The 3VNF Series of tunable bandreject filters are available as high "Q", three section, tunable cavity filters.
The series covers the frequency range of 25 to 2500 MHz. Each model is tunable over an octave bandwidth with notch depths of at least 45 dB.
The units are tuned via a knob with a dial calibrated in MHz and accurate to ±1%. Passband loss is typically less than 0.5 dB and passband VSWR is typically less than 1.2:1. SMA connectors* and 50 Ohm impedance will be considered standard. Units are housed in an aluminum case with high "Q" cavities.
These filters can be used to eliminate undesired signals as close to the passband as 500 kHz for the low band unit and 3 to 8 MHz for the 500 to 1,000 MHz band. For special requirements not covered by these standard models, please contact the factory. These units are ideally suited for precision test & measurement environments.
