Abstract:
1. A method of configuring a wireless communication device to receive signals in a plurality of signal bands, comprising: determining a required gain for each of the plurality of signal bands; determining a required noise figure for each of the plurality of signal bands; determining an impedance for each of the plurality of signal bands as seen by a single amplifier that will approximately result in the required gain and noise figure for each of the plurality of receive signals when amplified by the amplifier; configuring receive signal paths associated with each of the plurality of signal bands so that the appropriate determined impedances are presented to the amplifier when the amplifier is receiving signals in a particular signal band; selecting an input impedance of the amplifier to broaden a pass band of the amplifier; and offsetting any reduction in noise figure for each of the receive signal paths by reducing the insertion loss for each of the receive signal paths by configuring the wireless communication device to use a single image rejection filter.
