SPDT Failsafe Switch

0.1 to 12 GHz

The GRF6018 is a linear, ultra-low loss SPDT Switch that has been designed with failsafe characteristics when all voltage inputs are removed. In switching mode, the device delivers IP0.1dB levels greater than 1 Watt along with high IIP3 levels for both RF paths.

When powered down (failsafe mode), RFC to RF1 defaults to a high insertion loss while RFC to RF2 defaults to a low insertion loss state that retains high linearity.

With optimization of external components, the upper frequency range of the device can be extended to 12 GHz and lower down to 100 MHz. Data plots using this high frequency tune are also included on the following pages. Optimization for a particular band essentially involves selecting the optimal series capacitor values (M1, M6, M7) for the three RF Ports.

The device is operated from a supply voltage of 3 volts to 5 volts with the single control input (V_SELECT) from 3 volts up to V_CC.
