11. RF Section Part of radio receiver, receives incoming RF electrical-magnetic signal. Very broad
banded, amplifies input signals. Most noise is produced here.
12. Mixer Part of radio receiver, heterodynes received signal with signal produced by local
oscillator circuit. Output contains the sum and difference frequencies.
13. IF Section Part of radio receiver, uses a set frequency throughout. Amplifies desired tuned
frequency.
14. 10.7 MHz Commonly used FM Radio Frequency
15. 44 MHz Commonly used Television Frequency
16. 1.6, 3.35, 9, and Commonly used Short Wave Radio Frequencies
40 MHz
17. Detector Circuit Part of radio receiver, made of a diode; rectifies incoming RF signal.
18. AGC/AVC Section Part of radio receiver, samples the signal at the detector and develops a control
voltage that is fed back to the first IF Amp. Ideally, amplifies weak incoming signals
and attenuates strong ones, allowing a constant, desirable output volume.
19. AF Section Part of radio receiver, audio amplification network that drives speakers. The load
must match the radio's circuitry with proper impedance matching.
20. Dipole Used as reference and as a comparison in measuring "gain" of another antenna.
21. Yagi "Beam" antenna that focuses all of its energy in a narrow beamwidth. The more
director elements present, the higher the gain rating and narrower beam width.
22. D Layer Approximately 30-50 miles above the earth, most prevalent during daylight hours.
Absorbs radio signals under 10 MHz.
23. E Layer
