I am attempting to simulate the following circuit. The MOSFET does not completely go off and the sin wave still leaks through the circuit even in the off state. Moreover, the output signal's amplitude is severely attenuated when the transistor is in the on state.
This phenomenon can be observed in the provided figure. I have attempted to use multiple MOSFETs however the results are similar. My input signal is 915MHz and is the net V(n011) in the figure. Please suggest a suitable MOSFET that would work for this particular frequency.
