@bjacobse RF circuit is mine, based on many simulations etc., so I can't fall back on 3rd party designs. Yes, it will have to be certified globally, as much as possible. I've been involved with the approval cycle in the past, so I'm familiar with how this works. I'm too old for financial involvements with other people, so I'll just have to see what "shakes out". I'm "beating the bushes" now for potential manufacturers who may want to procure the design outright. Thanks for your input.
