Patent ID: 7333831

Claim:
A communication system having band swappable receive inputs, comprising: receive path circuitry within an integrated circuit chip having: one or more low noise amplifiers (LNAs) each having an input pin and each being configured to operate in multiple frequency bands with a performance degradation of lower than 1.0 dB between frequency bands and each configured to receive multiple frequency bands on a respective LNA input pin; and control circuitry to provide one or more control signals to select a single frequency band of operation for respective LNAs; and external circuitry coupled to the respective LNAs, the external circuitry having a filter stage and an input match stage configured for the multiple frequency bands for each respective LNA; and a printed circuit board (PCB) that couples the integrated circuit to the external circuitry via fixed connections, each of the fixed connections connecting the external circuitry to one of the input pins of the LNAs.
