5 MM5130 – DC to 26 GHz High Power RF Switch | March 24, 2021 v2.0Normal SP4T Mode The MM5130 is normally configured as a SP4T, with input on the RFC channel. The RFC is then routed to one of the 4 outputs by biasing the desired RFxGATE pin.

This configuration is called super-port. It consists of bypassing the RFC input port and using the remaining 4 channels as a symmetrically oriented SP3T (or SPST or SPDT if preferred). In this manner, any one of the RF1, RF2, RF3, RF4 channels can be connected to any other channel by biasing both desired channels. When operating in super-port mode, slight improvements in RF isolation and return loss can be achieved. Please refer to the “Recommended PCB Layout” section with instructions on how to optimize the PCB layout for super-port mode.
