BODY BIAS SWITCHING FOR AN RF SWITCH
First Claim
1. Radio frequency (RF) switching circuitry comprising:
- a first switch comprising a first control contact, a first switch contact and a first body contact;
a body switching network operably associated with the first switch, the body switching network comprising;
a first switchable path connected between the first body contact and the first control contact;
a second switchable path connected between the first body contact and the first switch contact.

Abstract
Embodiments of radio frequency (RF) switching circuitry are disclosed that include (at least) a first switch and a body switching network operably associated with the first switch. The first switch has a first control contact, a first switch contact and a first body contact. The body switching network includes a first switchable path and a second switchable path. The first switchable path is connected between the first body contact and the first control contact of the first switch. Additionally, the second switchable path is connected between the first body contact and the first switch contact. Accordingly, the first body contact is can be appropriately biased by the switchable paths without requiring a resistor network and thus there is less loading. This maintains the Q factor of the RF switching circuitry.

21. A method comprising:
-
opening a first switch; closing the first switch; closing a first switchable path when the first switch is open, wherein the first switchable path is connected between a first body contact of the first switch and a first control contact of the first switch; opening the first switchable contact path when the first switch is closed; opening a second switchable path when the first switch is open, wherein the second switchable path is connected between the first body contact of the first switch and a first switch contact of the first switch; and closing the second switchable path when the first switch is closed.
