<p>A circuit, a method and an apparatus, are described. A radio frequency, RF, signal received from a transmission line (606) is provided to the source of a transistor (624a) in a common-gate amplification circuit (624). A series resonance (632, 634) connected to the source provides a low impedance path to ground for interfering RF components in the RF signal. The series resonance (632, 634) is tuned to provide a high impedance to a band of frequencies centered on a frequency of interest and to shunt interfering RF components outside the band of frequencies centered on the frequency of interest. The interfering RF components may include a harmonic of the frequency of interest.</p> |
