Meaning and Definition
A radio receiver design that converts incoming radio signals to a fixed intermediate frequency (IF) to simplify amplification and filtering.
A highly sensitive and selective electronic circuit that has been the standard architecture for radio, television, and radar receivers since its invention in the early 20th century.
Dialectal Variation
British vs American Usage
Differences
No difference in terminology. Spelling of related terms (e.g., "centre frequency" vs. "center frequency") follows regional norms.
Connotations
Identical technical connotations in both dialects.
Frequency
Equally rare in both UK and US non-technical speech. Slightly more frequent in UK engineering contexts historically due to pioneering work by UK inventors.

FAQ
Frequently Asked Questions
It was invented by Edwin Armstrong in 1918.
Yes, 'superhet' is a common and acceptable abbreviation in technical and hobbyist contexts.
It provides superior selectivity (the ability to separate close stations) and sensitivity compared to earlier designs, making modern clear radio reception possible.
Modern devices often use advanced variants or digital signal processing, but the fundamental superheterodyne principle is still foundational in many RF (radio frequency) front-end designs.
A radio receiver design that converts incoming radio signals to a fixed intermediate frequency (IF) to simplify amplification and filtering.
Superheterodyne receiver is usually technical/specialist in register.
Superheterodyne receiver: in British English it is pronounced /ˌsuːpəˈhɛt(ə)rə(ʊ)ˌdʌɪn rɪˈsiːvə/, and in American English it is pronounced /ˌsupərˈhɛdərəˌdaɪn rɪˈsivər/. Tap the audio buttons above to hear it.

Learning
Memory Aids
Mnemonic
Imagine a SUPER chef (HETERO) making a DYNE-amite sandwich by first converting all ingredients into an intermediate, easy-to-handle paste (IF) before final assembly.
Conceptual Metaphor
A universal translator: it takes many different foreign languages (radio frequencies) and first translates them all into one common language (the intermediate frequency) for easy processing.
