... For applications in which input power levels vary over a wide range, it may be useful to dynami- cally adapt the bias of the MGA-71543 to match the signal level. A sensor senses the signal level at some point in the system (usually in the baseband circuitry) and automatically adjusts the bias current of the amplifier accord- ingly ...

... If a lower current is drawn, the gain of the amplifier is significantly reduced and the performance will degrade. If the device current is set to zero, the MGA-71543 is switched into a bypass mode in which the signal is routed around the amplifier with a loss of about 5.6 dB. The simplest way of switching the ...

... For low noise amplifier application, the LNA is typically biased mA. The MGA-71543 is a conditionally stable device, therefore, the proper input and output loads must be presented in addition to properly RF grounding the device. Please refer to the stability section for tips on preventing oscillation ...
Page 18
... Design for Stability The main potential for oscillation with the MGA-71543 is improper grounding and/or improper RF bypass capacitors. Any device with gain can be made to oscillate if feedback is added. Proper grounding may be achieved by minimizing inductance paths to the ground plane ...
