  • Radio frequency device with fast charging of an input capacitance
    Patent number: 6438364
    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.
