Since then, until quite recently, the Superhet design has been at the heart of a majority of commercial radio receivers. Direct Conversion Receivers were devised around 1930, but required ...

In a world with software-defined radios and single-chip receivers, a superheterodyne shortwave radio might not exactly score high on the pizzazz scale. After all, people have been mixing ...

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 ...

All later television receivers were of the superheterodyne type. In fact, all radios, television receivers, terrestrial and satellite, and all radar sets employ this superheterodyne principle, ...

Maxim introduced the MAX7033, the newest 300MHz to 450MHz superheterodyne ASK receiver. This devices features a high sensitivity of -114dBm, user-selectable center-frequency image rejection of better ...

the homodyne receiver was one of the earlier methods of building radios, both of which were superseded by the superheterodyne approach. See superheterodyne receiver. THIS DEFINITION IS FOR ...

FAA (Federal Aviation Administration) regulations generally forbid the use of receivers onboard commercial aircraft because a superheterodyne receiver's local oscillator can radiate signals that could ...

This report describes a rack-mounted superheterodyne receiver covering the medium and long-wavebands, which has been developed by the Research Department for use in conjunction with the Muirhead ...

A micro-wave radiometer, built especially for the purpose, consists mainly of a double superheterodyne receiver with pass band of 17 kc., the band being shifted back and forth through 75 kc.
