However, most of JFW’s test system business involves custom designed models. JFW does not charge NRE’s for custom models. We encourage you to email us your requirement ([email protected]). We will respond with a ROM (rough order of magnitude) quote in 1-2 days. Please include a block diagram with your request if the test system involves multiple RF components.
