Unlicensed intentional radiators are certified under FCC Rules Part 15 Part 2, and neither Class A or Class B applies to the wireless device itself. Limits are different for the various types of intentional radiator, and the appropriate rule sections must be applied. If there is a digital device

We are looking for a gasket to place between the faceplate of our product and and usb connector shell. Due to mechanical tolerances the connector does not always make contact with the faceplate. Because of this we fail contact esd when applied between the connector shell and the faceplate. We

Does anyone have experience with Pulse Start Metal Halide lights? It appears as if they took the unreliable starter electrode, bi-metal switch and resistor out of the bulb and somehow use a high voltage pulse from the ballast to start the bulb. One major advantage is the bulbs hot re-start much

Do we need FCC logo for the PCBAs alone

Dear Experts, We plan to sell a PCBA alone to a OEM customer in US. Our OEM customer will integrate this into their main product and then sell in the market. This OEM customer will obtain FCC approval (DoC route) for the integrated product. Our PCBA will never be available to any end user.

Are Class A emission limits applicable to FCC Part 15 Sub part C

Dear Experts, Emission limits for Class A digital products are not given for intentional radiators in FCC Part 15 sub part C. Does it mean all intentional radiators must be Class B digital devices? A device for which the fundamental emissions are within the limits as per section

I recall that there are type approvals for intentional radiator sub-assemblies that could make your customer's job easier. However, I think this would only apply if the antenna was embedded on your PCBA and they didn't use an external antenna. As to whether or not this is different from

ATE equipment in China

I was asked if an ATE company can sell non-certified test equipment to a U.S. based company and if the U.S. Based company can then ship the equipment for use at their plant in China. I didn’t think they could do this but I’d like to have the opinion of the experts here. This does not have anything

Bill, is correct (as usual) but I would like to bring your attention to 15.225(d) which states that the spurious emissions (outside of the modulation mask) from the intentional radiator portion of the equipment are covered under 15.209. The emission limits in 15.209 are the same as the Class B
