Abstract:
1. A radio-frequency (RF) switch comprising: first and second field-effect transistors (FETs) connected in series, each of the first and second FETs having a gate node and a body node; a gate-coupling path that couples the gate node of the first FET to the gate node of the second FET, the gate-coupling path including a first capacitor having a first end coupled to the gate node of the first FET and a second end coupled to the gate node of the second FET; a body-coupling path that couples the body node of the first FET to the body node of the second FET, the body-coupling path including a second capacitor having a first end coupled to the body node of the first FET and a second end coupled to the body node of the second FET; and an adjustable-resistance circuit connected to the body nodes of the first and second FETs, the adjustable resistance circuit including a parallel combination of a first resistor and a bypass switch.
