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 IP1dB levels greater than 1 Watt along with >49 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.
