摘要： An integrated circuit (IC) includes a first switch, a second switch, and an amplifier electrically connected between the first switch and the second switch. An RF signal path passes through first switch, the amplifier, and the second switch in this order. The IC includes an input terminal and an output terminal that are to be connected to each other between the first switch and the amplifier or between the amplifier and the second switch outside of the IC with a component connected therebetween. In a top view of the IC, a first region of the first switch, a second region of the amplifier, and a third region of the second switch are disposed on a straight line such that a virtual straight line connects any point of the first region, any point of the second region, and any point of the second region in this order.

摘要： A radio frequency switch apparatus includes a radio frequency switch, a dynamic bias circuit, and a switch control circuit. The radio frequency switch includes a first radio frequency switch circuit connected between a first signal terminal and an input terminal. The first radio frequency switch circuit includes a series switch and a shunt switch. The dynamic bias circuit is configured to generate a bias voltage and a buffer voltage lower than a battery voltage by a preset voltage, using the battery voltage and configured to output the bias voltage to a signal line connected to the input terminal. The switch control circuit is configured to generate first and second gate voltages to switch the first radio frequency switch circuit, based on a band selection signal, using the battery voltage and the buffer voltage.

摘要： A switching apparatus alternately connects a mobile radio module and an E-Call controller to an antenna/ The switching apparatus includes a first signal input, a second signal input, an antenna connection and a changeover device that changes between a first switching state and a second switching state, based on at least one switching signal. In the first switching state, only the first signal input is electrically connected to the antenna connection, and in the second switching state, only the second signal input is electrically connected to the antenna connection. To prevent a connected transmission devices from diagnosing decoupling from the antenna connection as a fault, in at least the second switching state the changeover device electrically connects the signal input that is decoupled from the antenna connection to a terminating device which emulates an antenna at the signal input that is connected to the terminating device.

摘要： A monolithic integrated circuit includes first and second pluralities of parallel-connected transistor elements (e.g., transistor fingers). To spread heat in the IC, the first and second pluralities of transistor elements are interleaved with each other and arranged in a first row. The IC also may include third and fourth pluralities of parallel-connected transistor elements arranged in a second row. The transistor elements in the first row may be series and shunt transistors of an RF switch transmit path, and the transistor elements in the second row may be series and shunt transistors of an RF switch receive path. During a transmit mode of operation, the series transistors in the transmit path and the shunt transistors in the receive path are closed. During a receive mode of operation, the shunt transistors in the transmit path and the series transistors in the receive path are closed.
