RADIO FREQUENCY SWITCH WITH IMPROVED SWITCHING TIME

摘要

A radio frequency (RF) switch which comprises an RF domain section having a plurality of RF switching elements. A DC domain section is provided having circuitry configured for controlling the RF switching elements in response to one or more control signals. A resistive load is provided between the RF domain section and the DC domain section. A bypass circuit is configured for selectively bypassing at least a portion of the resistive load.

1. A radio frequency (RF) switch comprising:
an RF domain section having a plurality of RF switching elements; a DC domain section having circuitry configured for controlling the RF switching elements in response to one or more control signals; a resistive load provided between the RF domain section and the DC domain section; and a bypass circuit configured for selectively bypassing at least a portion of the resistive load, wherein the bypass circuit comprises a detection stage for determining when to activate the bypass circuit, and the detection stage is operable for detecting when at least one signal derived from the one or more control signals is transitioning between logic states.
