Resonant, Inc (RESN)

[Scandle34]

Every cell phone has a number of these filters - most designs use a filter for each LTE or 5G frequency band. It's a large number of filters per phone and a large number of phones (and iot devices, etc.). Individually the filters cost pennies and the income to Resonant is a small slice of that, but the numbers are large.

Like I said though, I have a very small position and have not run the numbers.
