dual-conversion receiver



  • A superheterodyne receiver in which there are successive frequency conversions utilizing two local oscillators, and thus having two intermediate frequencies. The first intermediate frequency is higher, for adequate image rejection, while the lower second intermediate frequency provides high selectivity and gain. Also called dual-conversion superheterodyne receiver, double-conversion receiver, double-conversion superheterodyne receiver, double superheterodyne receiver, or triple-detection receiver.
