Title:
RADIO FREQUENCY DEVICE WITH FAST CHARGING OF AN INPUT CAPACITANCE
Document Type and Number:
WIPO Patent Application WO2001095485
Kind Code:
A3
Abstract:
A radio frequency device has an input transistor from which a capacitance is seen, and a fast charging circuit for charging the capacitance. The input transistor receives a radio frequency signal. The capacitance is quickly charged when the device is switched from off to on and/or from low gain to high gain, thereby reducing the switching-on time of the device.
