Super regeneration is based on an oscillator in on / off operating mode. When it is switched on, the oscillation phase is preceded by a short period of very high sensitivity. The time required for oscillation to begin is then a function of the external energy input to the oscillator (detection of an incident carrier). When it is in amplifier mode, super regeneration does not permit a class A consumption, it switches to class C as soon as the oscillations start. A high amplification of its current image therefore reproduces the variations of the incident wave constituting modulation.
Very economical structure: a single HF stage + an AOP
Very low consumption possible.
ASK detection only
Wide passband (several MHz)
Radio characteristics difficult to control
High re-radiation (oscillatory phase)

Wake-up time of several seconds
Reduced temperature range
Widely dispersed manufacturing
Fields of use:
Household remote control
Automobile industry (security due to very high-level rotating codes)
Superheterodyne RF Receiver Module
The super heterodyne system is composed of a LF processing channel where each stage performs control of one of the radio characteristics. Selectivity is achieved by means of the Channel Filtering. The sensitivity is obtained by means of a high amplification channel. The choice of demodulator enables any type of modulation to be processed. Transposition of the radio spectrum received to the lower processing frequency is performed by means of one or more devices called Frequency changers.
