摘要： An amplifier arrangement with controllable gain includes a first and a second amplifier device which each have a control input to receive a control signal to adjust a gain factor of the respective amplifier device. A control device is provided which is coupled to the second amplifier device to derive an effective gain factor of the second amplifier device as a function of the control signal. The control device further includes a control output coupled to the respective control inputs of the first and the second amplifier device to provide the control signal depending on a desired gain factor and the effective gain factor.

摘要： This disclosure relates to low noise amplifiers (LNAs) and more particularly to LNAs integrated on integrated circuit (IC) chips along with radio frequency (RF) amplifiers. In one implementation, an impedance translator is coupled to an amplifier, the impedance translator to cause the amplifier to selectively amplify the one or more components of a received signal.
摘要翻译： 本公开涉及低噪声放大器（LNA），更具体地涉及集成在集成电路（IC）芯片上的射频（RF）放大器的LNA。 在一个实现中，阻抗转换器耦合到放大器，阻抗转换器使得放大器选择性地放大接收信号的一个或多个分量。
