Abstract
The present disclosure relates to a front-end system for a radio device, the front-end system comprising a low-noise amplifier (LNA), arranged for receiving a radio frequency input signal (RF) and arranged for outputting an amplified radio frequency signal (RF), wherein the low-noise amplifier comprises a first differential amplifier, and a mixer (MIX), arranged for down-converting the amplified radio signal (RF) provided by the low-noise amplifier (LNA) to a baseband signal (BB), by multiplying the amplified radio signal (RF) with a local oscillator (LO) frequency tone, said low-noise amplifier (LNA) and said mixer (MIX) being inductively coupled.
