In the context of power consumption of radio electronics, it is interesting to notice that almost all transceivers available today are based on the superheterodyne architecture. The superheterodyne has superior performance when it comes to sensitivity, but as monolithic integration and power consumption has come into play, the direct conversion receiver has become increasingly popular. The super-regenerative receiver is another alternative suggested for cheap, low data rate, communication. They propose a new radio technology, a system based on a receiver constantly in operation in low power mode.
