WebJul 29, 2024 · Larger devices with larger parasitic capacitance are required to reduce the on-state resistance. These large capacitors restrict the bandwidth and create unwanted signal coupling between nearby relays. The capacitance of a reed relay is considerably smaller than that of an SSR and, hence, a reed relay can more easily handle higher frequency ... Web8.1 Radio relay communication systems. The successful development of radio communications is accompanied by an increase in the speeds and volumes of transmitted information. For the transmission of increasing information flows with low losses, signals with a wider band are used, which requires an expansion of the frequency range occupied …
