Claim 0:
1. An integrated passive die comprising:
a substrate;
an input node and an output node; and
radio frequency (RF) filtering circuitry comprising a plurality of LC tank circuits coupled between the input node and the output node, each one of the plurality of LC tank circuits comprising:
an inductor comprising a metal trace over the substrate; and
a capacitor coupled in parallel with the inductor over the substrate, wherein a resonance frequency of the combination of the inductor and the capacitor is less than a self-resonance frequency of the inductor;

wherein for at least one of the plurality of LC tank circuits:
the metal trace of the inductor forms a loop between a first inductor node and a second inductor node; and
the capacitor is coupled across a gap of less than 0.5 cm between the first inductor node and the second inductor node such that the capacitor and the metal trace form a closed loop.
