Patent ID: 8521118

Claim:
A receiver arrangement comprising: an antenna that receives a radio-frequency signal; a first reception path comprising: a first bandpass filter with an input coupled to the antenna and an output; and a first preamplifier having an input coupled to the output of the first bandpass filter; and a second reception path comprising: a second bandpass filter with an input coupled to the antenna and an output; a second preamplifier having an input coupled to the output of the second bandpass filter; and a switch to turn on and to turn off the second preamplifier, wherein the second preamplifier comprises a common-emitter transistor, the common-emitter transistor including a base connection coupled to the input of the second preamplifier, a collector connection coupled to a common output node associated with the first and second preamplifiers, and an emitter connection coupled to a reference potential, and wherein the switch includes a first connection coupled to the base connection and a second connection coupled to the collector connection.
