RF switches act as an automated system for connecting or disconnecting one or more radio frequency signals. As an essential component in any radio frequency system, the purpose of an RF switch is to quickly make, break, or interrupt transmission paths between components. Generally, RF switches are used to control the routing of a signal in a device.

SKY13350-385LF is an SPDT/SP3T (Single Pole Double Throw (SPDT) / Single Pole Triple Throw (SP3T)) low-loss, high-isolation RF switch designed for operation in the frequency range of DC to 3.8GHz. This switch has an ideal combiner solution and can be used in various fields such as infrastructure, test and measurement, wireless communications, consumer electronics, etc.

Applications

The SKY13350-385LF can be applied in different industries as either a low-power switch or an high-power switch, and in different systems such as:

• Wireless Base Stations: It can be used to switch between the various subsystems, such as the transmitters and receivers in a base station.
• Test and Measurement: Used for signal switching in test fixtures, probes, and automated test systems.
• Satellite Communications: It can be used in switching between the transmit and receive channels in a satellite or trunked radio.
• Consumer Electronics: Used in switching between multiple antennas connected to a smart phone.
• WI-FI Networking: It can be used in switching between radio bands and channels in a WI-FI network.

Working Principle

The SKY13350-385LF switch works by applying a voltage to the pins representing the switch. Applying a voltage to a pin closes the switch, while applying no voltage opens the switch. Additionally, the switch is designed as a bypass in order to match the source and load impedances. An isolation pin is also provided to ensure good performance across the range.

The SKY13350-385LF is capable of handling power levels up to 5W CW, and 12dB return loss. It is also designed with low-loss and high-isolation which makes it an ideal switch for high power applications. The low-loss ensures that the switch does not degrade the signal when switching between sources.

Overall, the SKY13350-385LF is a highly reliable, low-loss, high-isolation RF switch which can be used in a wide variety of applications. Its wide frequency range and low power levels make it an ideal switch for various RF systems.
