Abstract:
1. A GPS receiver, comprising: an antenna configured to receive an input signal; a first amplifier configured to amplify the input signal, wherein the amplifier includes a terminal that presents a negative resistance to the input signal and thereby reflectively amplifies the input signal; a splitter configured to receive the amplified input signal and split the signal into a plurality of split signals; second amplifiers configured to selectively amplify or attenuate the plurality of split signals, each second amplifier including a first terminal that presents a negative resistance to at least one of the plurality of split signals and a second terminal that receives a control signal that controls the reflective amplification or attenuation of the respective split signal; and processing circuitry configured to demodulate the amplified or attenuated split signals and calculate positional data.
