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.
