A receiver includes a first amplifier having an input for receiving an RF signal, and an output for providing an amplified RF signal, a switch section that selectively switches the amplified RF signal onto a selected one of a plurality of nodes, and a filter section comprising a plurality of filters coupled to respective ones of the plurality of nodes. A first filter of the plurality of filters comprises a first variable capacitor coupled in parallel with an inductance leg between a corresponding one of the plurality of nodes and a power supply voltage terminal. The first variable capacitor has a capacitance that varies in response to a tuning signal. The inductance leg includes a first inductor in series with an effective resistance, wherein the effective resistance has a value related to an upper cutoff frequency to be tuned by the first filter.
