SPDT Failsafe Switch

0.1 to 6.0 GHz

The GRF6011 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 > 55 dBm 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 6 GHz. 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, M4, M5) for the three RF Ports.

The device is operated from a supply voltage of 3.0 volts to 5.0 volts with the single control input (V_SEL) from 3.0 volts up to V_DD.
