Choosing the Right Tunable Filter !!
Choosing the right filter requires the designer to consider many aspects. These aspects are related to technical performance, size/weight and cost. On the technical side, the filter performance characteristics can be summarized as follows.
Insertion loss
Bandwidth/selectivity
RF power handling
Intercept point (third order intercept)Tuning range
Tuning speed e power consumption
In addition, the size and weight of the filter must be considered, especially for portable and airborne devices. As always, cost is the main driver of engineering decisions
The tuning range of our four series of tunable filters, NANO, MINI, MAXI, and POWER, is based on popular communication frequency bands covering 1.5MHz to 3GHz. The standard 3dB bandwidth of the device is 1.8% to 20%, and a variety of packaging forms and sizes are available to suit different applications.
