摘要： A circuit is disclosed with an external coupling port for coupling to an external antenna, for example. The circuit has an FDD receive path including a narrowband passband filter. The circuit has a TDD receive path bypassing the narrowband passband filter but relying on a same amplifier. The circuit also has an FDD transmit path including a narrowband passband filter. The circuit has a TDD transmit path bypassing the narrowband passband filter of the FDD transmit path but relying on a same transmit amplifier. A switching configuration allows the circuit to operate in TDD mode, alternating between the TDD receive path and the TDD transmit path and in the FDD mode wherein the FDD transmit and receive paths are simultaneously coupled to the external coupling port.

摘要： The present invention relates to a bias circuit for biasing a depletion mode power transistor. The bias circuit includes a voltage offset circuit and a transistor, where the voltage offset circuit is serially coupled between the gate terminal of the depletion mode power transistor and the drain terminal of the transistor. The bias circuit generates a bias voltage that, when applied to the gate terminal of the depletion mode power transistor, maintains a substantially constant drain current through the power transistor over a range of threshold voltages caused by process and temperature variations.

摘要： A frequency converters used in communications receivers. Such frequency converters can be used for converting a signal from a Radio Frequency (RF) to a low frequency suitable for processing such as demodulation. The inventors have made the unexpected discovery that when the gates of the MESFETs of a double-balanced mixer are left open-circuited and allowed to self-bias, the drop in mixer linearity at high LO power levels is reduced thereby increasing the LO power range of operation. This invention can be used as an improved scale-down mixer as well as an upconverter mixer.

摘要： An integrated circuit packaging assembly for reducing the length of bond wires transmitting radio frequency signals is disclosed herein. The die is offset in the packaging to position a subset of its bond pads in close proximity to package bond pads to allow for shorter bond wires, which reduces the inductive reactance that is induced in longer wires by high frequency signals. The subset of the bond pads is used for RF transmissions, while the other bond pads are used for direct current and low frequency signals.
