RF switches are electronic switching devices used to connect or disconnect RF signals, creating on and off states. Similar to most electronic switches, RF switches are available in a variety of forms, from single poles and throws up to large multi-pole configurations. However, due to the specific nature of radio frequency signals, special attention must be paid to design features so that unwanted RF signal losses, and reliability concerns are addressed.

The SKY13567-666LF RF switch is a specialized type of electronic switch that can be used in a variety of applications requiring isolation control of RF paths. This device is an integrated GaAs FET and PIN diode single pole, double throw (SPDT) switch ideally suited for switching high speed logic signals. The switch features integrated gamma diodes, allowing reliable switching of high frequency signals with low signal transit through the switch.

The SKY13567-666LF provides two modes of operation, momentary and latch. Momentary operation creates a push-to-on, push-to-off behavior, ideal for transient switching of signals. Latch behavior acts like a "flip of a switch", with both on and off states accessible and controllable through the input pins, providing a more stable RF signal control. Regardless of mode, this switch features a low on-resistance value of 6.4ohms for high speed signals and a low capacitive off-state, providing improved signal fidelity.

This switch also features low insertion loss of 2.5 dB and low isolation of 11.2 dB across its frequency range of 1 to 2 GHz. With low on capacitance and off leakage current, the SKY13567-666LF is designed for use in a variety of critical RF signal pathways. These include but are not limited to: applications where signal integrity is paramount, such as microwave link systems and test and measurement instrumentation.

The Switch\'s control logic follows a voltage controlled logic level scheme, with a VCC from 3.0 V to 5.5 V controlling the on/off switching of the device. This guarantee\'s reliable operation for a variety of voltage sources and logic systems, while the device only consumes 10 mA, ensuring efficient operation.

The SKY13567-666LF RF switch is an excellent choice of device for applications that require reliable RF signal switching. With a low on resistance, low insertion loss and low capacitance off-state, the SKY13567-666LF is well suited for use in a variety of RF signal pathways. With the ability to provide both momentary and latch modes of operation and with integrated control logic, this switch is an ideal choice for applications where quick, reliable RF signal routing is necessary.
