Q14：What are the advantages of helical filter?

Helical filter is a Bandpass style RF filter, the common mount by thru-hole package. To compare it with LC/ceramic/saw/cavity bandpass filter, it has better performance (high Q, high attenuation, low loss etc) in a tiny dimension, and users can slightly tune frequency on helical filter accordingly to design board of devices or equipments' on site signal need.

For new (frequency) design at samples or prototypes stage don't need to spend huge mold opening costs, and future large scale (mass) production doesn't require 10K, 50K, we accept trial and mass production in 50, 100, 200 ... pcs, if constraints on sample budget, we can propose special scheme for you by discussion.

Production lead time is much shorter, including we can help users to tune frequency if across range wider than designs and in few units per frequency is ok.
