Noun
superheterodyne receiver (plural superheterodyne receivers)
A radio receiver that mixes (beats or heterodynes) a locally produced frequency with the incoming frequency
At the cost of an extra frequency converter stage, the superheterodyne receiver provides superior selectivity and sensitivity compared with simpler designs. Source: Internet
