    Abstract: A protection circuit and method for protecting driven circuitry against voltage peaks in a radio frequency signal, “VRF”, past a predetermined voltage level “Vdetect”. The protection circuit includes an input for receiving the radio frequency signal. The protection circuit also includes at least one amplification stage coupled to the input. The amplification stage is operable to produce an amplified signal based on Vdetect−VRF. The protection circuit further includes a hold circuit operable to determine, from the amplified signal produced by the amplification stage, whether a peak voltage Vpeak of the radio frequency signal exceeds Vdetect. The hold circuit is operable to output a first detection value if Vpeak exceeds Vdetect. The hold circuit is operable to output a second detection value if Vpeak does not exceed Vdetect. The protection circuit also includes a latch circuit operable to latch the detection value outputted by the hold circuit.

    Abstract: An RF amplifier for implementation in SiGe HBT technology is described. The RF amplifier has a cascode stage comprising a common base (CB) transistor and a common emitter (CE) transistor arranged in series between a first voltage rail and a second voltage rail. An RF input is coupled to the base of the CE transistor and an RF output is coupled to the collector of the CB transistor. The RF amplifier includes a CB power-down circuit arranged between the base of the CB transistor and the second voltage rail and a CE power-down circuit arranged between the base of the CE transistor and the second voltage rail. In a power-down mode the CE power-down circuit couples the base of the common-emitter-transistor to the second voltage rail. The CB power-down mode circuit couples the base of the CB transistor to the second voltage rail via a high-ohmic path.
