Abstract

A carrier generator for generating a carrier at a frequency of interest in a wireless communications system. The carrier generator comprises a first oscillator configured to generate the carrier. The first oscillator exhibits a first impedance and comprises an energy storage tank, an amplifier, at least one trimming pin and at least one capacitor. The energy storage tank is configured to generate a first periodic signal. The energy storage tank includes at least one inductor and at least one capacitor. The amplifier coupled with the energy storage tank and is configured to amplify an amplitude of the first periodic signal. The at least one trimming pin is configured to adjust the at least one capacitor of the energy storage tank, and the at least one modulation pin is configured to receive a modulation signal. The carrier generator further comprises an antenna exhibiting a second impedance smaller than the first impedance, and a network coupled between the first oscillator and the antenna. The network includes at least one inductor or at least one capacitor and being configured to provide a third impedance such that a resultant impedance of the second impedance and the third impedance as viewed from the first oscillator toward the antenna is large enough to facilitate the first oscillator to generate the carrier at the frequency of interest.
