PIN Switches and PIN Switch Drivers

Overview

RF and Microwave switches (RF switches) are used to direct RF and Microwave signals between a common port and a number of individual ports ranging from just a single port (Single Pole Single Throw – SPST) to many ports such as a SP6T (Single Pole Six Throw). The common port can be connected to either input signals as in the case of a common antenna or the input to switched filters, or as an output as might be the case to select a particular output from several filters. A common usage is that of a Transmit/Receive switch (T/R) in which the common port acts as the input to the receiver and the output of the transmitter, shown diagrammatically in figure 1a. Such usage puts constraints on the design as transmitters often handle high power whereas receivers require good low signal level performance and isolation from any high power from the transmitter. Figure 1b shows a multi-pole switch configured for a switched filter.
