RECEIVER FRONT-END WITH LOW POWER CONSUMPTION

摘要

Receiver (20) comprising a mixer (23) with a first input, a second input and one output. An input signal (SRF(t)) comprising a high frequency component fRF is applied to the first input, and a local oscillator signal (SLOnew(t)) is applied to the second input of the mixer (23). The local oscillator signal (SLOnew(t)) is generated by a source (30) and the local oscillator signal (SLOnew(t)) has a frequency component with a frequency fLo11 . The frequency fLOnew is at least three times lower than the frequency fRF of the input signal (SRF(t)). The mixer (23) provides for a down-conversion of the input signal (SRF(t)) to a lower frequency band.
