摘要: Electronic circuits and methods are provided for various applications including signal amplification. An exemplary electronic circuit comprises a MOSFET and a dual-gate JFET in a cascode configuration. The dual-gate JFET includes top and bottom gates disposed above and below the channel. The top gate of the JFET is controlled by a signal that is dependent upon the signal controlling the gate of the MOSFET. The control of the bottom gate of the JFET can be dependent or independent of the control of the top gate. The MOSFET and JFET can be implemented as separate components on the same substrate with different dimensions such as gate widths.

摘要: RF switching devices are provided that alternatively couple an antenna to either a transmitter amplifier or a receiver amplifier. An exemplary RF switching device comprises two valves, one for a receiver transmission line between the antenna and the receiver amplifier, the other for a transmitter transmission line between the antenna and the power amplifier. Each valve is switchably coupled between ground and its transmission line. When coupled to ground, current flowing through the valve increases the impedance of the transmission line thereby attenuating signals on the transmission line. When decoupled from ground, the impedance of the transmission line is essentially unaffected. The pair of valves is controlled such that when one valve is on the other valve is off, and vice versa, so that the antenna is either receiving signals from the power amplifier or the receiver amplifier is receiving signals from the antenna.
