Another way to further reduce signal path and increase RF performance is to package more than one relay in a package. In the top image shown here two CRF reed relays are in line. The signal path goes from A to B. As the signal leaves the first CRF reed relay it goes down to the PCB and then traverses the short distance to the second CRF relay, where it then goes up the lead and into the second CRF relay. In Standex Electronics’ RM Series shown in the lower image, there are two relays within series packaging, so the leads never exit the package. The signal simply goes from one reed relay directly to the next relay, all on the same plane, further reducing the signal path.
