RF switches are electronic components that enable and disable signal paths in electronic circuits, usually made up of semiconductor components. They direct signals between multiple ports by controlling the enablement and disablement of transmission paths in an electronic circuit. Most RF switches are integrated circuits found in electronic devices such as computers, cell phones and MP3 players. Because of their small size and low power requirements, RF switches can be used in portable electronic devices.

The PE42723A-Z is a type of RF switch developed by Panasonic that is especially suitable for portable electronic devices and consumer-grade applications. It is an SP6T (Single Pole, Six Throw) switch, meaning that it can connect up to six different input ports to one output port. It is designed to support the frequency range from 0.25GHz to 2.7GHz and has an insertion loss of less than 0.6 dB and isolation of greater than 15.5 dB.

The application field of the PE42723A-Z is primarily consumer grade and mobile device applications. It is often employed in wireless communication links, such as cell phones or house-to-car radio connections. Other possible implementations include analog or digital broadcast receivers, amplified cellular antennas, USB 3.0 signal multiplexers, amplifier designs, and portable navigation systems. The PE42723A-Z is also suitable for applications in military devices and medical equipment due to its high port-to-port isolation of 15.5dB.

The working principle of the PE42723A-Z is based on the use of a single-pole, six-throw switch, or SP6T. The SP6T switch has six ports, identified as 1-6, arranged in two rows, with three ports in each row. This switch is available in normally open (NO) and normally closed (NC) variants, with choice of normally open or normally closed ports. When the switch is enabled, the selected ports are connected to the first port, 1, while the remaining ports are disconnected.

The PE42723A-Z switch uses an integrated circuit to control the switching of each port. This integrated circuit can be controlled by a microcontroller, such as an Arduino board, to select ports and enable them. The integrated circuit uses a multiplexer to control the switching of the six ports. Each port is connected to a multiplexer selector line, and depending on which selector line is asserted, the appropriate port is connected to port 1.

The PE42723A-Z switch is a very useful component for creating wireless communication links in various consumer grade and mobile device applications. It can provide a high degree of port-to-port isolation to prevent interference between signals, and its small size and low power requirements make it ideal for use in portable electronic devices. With the use of a microcontroller for control, the PE42723A-Z switch can be used to create many different kinds of wireless communication links with ease.
