Indiana Microelectronics offers an array of tunable filters to fit your testing and implementation needs operating from fmin @ 108 MHz to fmax @ 2120 MHz. Leveraging quasiabsorptive techniques in conjunction with lumped element topologies enables these filters to be optimized for tuning range, bandwidth, and SWaP.

- Frequency range is defined as the passband between the 3 dB insertion loss points outside of the notch filter tuning range.
- Insertion loss is defined as the maximum insertion loss within the passband of the notch filter tuning range.
- Maximum return loss in the passband frequency range outside of the notch or within the bandpass.
