direct conversion receiverAlso called a "tuned radio frequency" (TRF) receiver, it is a radio receiver that detects and demodulates the carrier signal broadcast by the station without using an intermediate frequency (IF) stage. A variable filter is tuned to filter out everything but the desired radio station's carrier frequency. Along with the homodyne receiver, direct conversion was one of the earlier methods of building radios, both of which were superseded by the superheterodyne approach. See superheterodyne receiver.

The SKY74400 power transceiver is a highly integrated GPRS device for quad-band applications containing a direct conversion receiver and power amplifier (PA) with an integrated PA control (iPAC[TM]) function in a compact, 6 x 11 mm multi-chip module (MCM). Oleg Panfilov, our Chief Scientific Officer, this patent should help us in our efforts to protect certain aspects of our direct conversion receiver technology. A direct conversion receiver can serve multiple applications with system differentiation occurring in software or firmware. |
