The Superheterodyne design, devised in 1918, was superior, but more expensive at that time. Cost considerations led adoption of the Superhet design to lag behind TRF until almost 1930. Since then ...

We’d say there are several common architectures for receivers and one of the most common is the superheterodyne. But what does that mean exactly? [Technology Connection] has a casual explanation ...

The carrier frequencies for AM operate from 530 kHz to 1610 kHz. Many superheterodyne AM radios use a demodulation circuit designed for 455 kHz. When the listener tunes in a station, an oscillator ...

The nonlinear device executing the heterodyne process is called a frequency mixer or frequency converter. In a superheterodyne transceiver, the frequency translation processes may be performed more ...

STL has investigated many transceiver/receiver topologies including quasi-monostatic to bistatic instrumentation radars as well as various receiver architectures ranging from ultra-stable low-noise ...

Another American inventor, Edwin Armstrong, developed the superheterodyne circuit in 1918, and in 1933 discovered how FM broadcasts could be produced. FM provided a clearer broadcast signal than ...

Along with the direct conversion receiver, the homodyne receiver was one of the earlier methods of building radios, both of which were superseded by the superheterodyne approach. See ...

Edwin Howard Armstrong (1890-1954), the inventor of the "Regeneration" and "Superheterodyne" circuits as well as "Frequency Modulation," or FM. A flamboyant man with a fondness for fast cars and a ...

RF frequency range is the range of input (RF) frequencies that the mixer was designed to work with. A LO (Local Oscillator) is an oscillator used in superheterodyne receivers which when mixed with an ...
