1results about "Reversible analogue/digital convertors" patented technology

A hybrid wideband / narrowband direct digital transceiver. In an example, the transceiver includes a first-stage downconverter configured to convert a radio frequency (RF) input analog signal to a first intermediate frequency (IF1) narrowband (NB) input analog signal; a second-stage downconverter configured to convert the IF1 NB input analog signal or a millimeter wave (mmW) input analog signal to a second intermediate frequency (IF2) NB input analog signal; one or more analog to digital converters (ADCs) configured to convert one or more of the IF1 NB input analog signal, the IF2 NB input analog signal, and the RF input analog signal to digital input signals; and a processor configured to control the first-stage downconverter to set a center frequency and bandwidth of the IF1 NB input analog signal and control the second-stage downconverter to set a center frequency and bandwidth of the IF2 NB input analog signal.
