Shortening the signal path will improve the RF characteristics of the reed relay. Standex Electronics’ LP Series was one of the first RF relays. With new relay designs Standex Electronics has dramatically reduced the overall signal path. The signal path starts at the bottom of the PCB at point A, goes thru the PCB, up into the junction of the reed switch, thru the reed switch and down to the bottom of the PCB. The distance within the relay from point A to B is approximately 0.8 inches with the added length from the bottom of the PCB on both sides and up into the relay. This offers much room for improvement as will be shown next.
