Abstract

An integrated circuit including one or more radio frequency (RF) filters to receive an RF signal and to generate a filtered RF signal and a down conversion stage coupled to the RF filters, the down conversion stage further including a local oscillator circuit and an intermediate frequency (IF) filter, the local oscillator circuit being electrically shielded from the IF filter. Each RF filter is a discrete inductive-capacitive (LC) filter, further including a plurality of discrete inductive banks and capacitive banks. The integrated circuit further includes a plurality of input pads to receive the RF signal, each capacitive bank of the RF filter being located adjacently to respective input pads within the circuit, and further includes a plurality of capacitor devices coupled in parallel, with capacitor devices having a lower capacitance value being positioned adjacently to said respective input pads and remaining capacitor devices being positioned in increased order of their capacitance value away from said respective input pads.
