Abstract:
Methods and systems for receiving signals via a multi-port distributed antenna are disclosed and may include selectively enabling one or more low noise amplifiers (LNAs) coupled to the antenna. The selective enabling may be based on a desired gain level applied to a signal received from the antenna. The LNAs may be coupled to ports on the antenna based on an input impedance of the LNAs and an impedance of the ports. Each of the LNAs may be configured for optimum linearity in different gain ranges, which may be proportional to the input impedance of the LNAs. The antenna may be integrated on a chip with the LNAs, or may be located external to the chip. The antenna may include a microstrip antenna. The LNAs may include variable gain and may be enabled utilizing a processor. Linearity on demand may be enabled via the selective enabling of the LNAs.
