More Information on Modulators / Demodulators...
What is a Modulator / Demodulator?
A radio frequency modulator (or RF modulator) takes a baseband input signal and then outputs a radio frequency modulated signal.This is often a preliminary step in signal transmission, either by antenna or to another device such as a television.A demodulator is a circuit that is used in amplitude modulation and frequency modulation receivers in order to separate the information that was modulated onto the carrier from the carrier itself.A demodulator is the analog part of the modulator.A modulator puts the information onto a carrier wave at the transmitter end and then a demodulator pulls it so it can be processed and used on the receiver end.
Types of Modulators / Demodulators
There are many different kinds of modulators / demodulators.At Future Electronics we stock many of the most common types categorized by supply voltage, operating frequency, signal-to-noise-ratio, packaging type and power dissipation.The parametric filters on our website can help refine your search results depending on the required specifications.The most common sizes for power dissipation are 33 mW and 200 mW.We also carry modulators / demodulators with power dissipation up to 600 mW.Operating frequency can range from 455 kHz to 2500 MHz, with the most common ranges being 460 to 880 kHz and 1 to 100 MHz.

Applications for Modulators / Demodulators:
Modulators / demodulators can be found in aerospace and defense, wireless, and broadband communications applications.Amplitude modulation (AM) and frequency modulation (FM) are used to carry information on a carrier.FM offers greater clarity for audio, and a wider bandwidth.One application where FM and digital are not suitable is aviation communications, which still uses AM.The reason is because weaker signals can be heard over stronger, closer ones with amplitude modulation, allowing for emergency transmissions to have a better chance of being heard over other traffic.AM uses a narrower bandwidth than FM.This is important for lower radio frequencies, where space is costly.
DIP Switches Applications
Typical Dip Switch applications include: Telecommunications, Computer Motherboards, Remote controls for frequency setting (like garage door openers) and other electronic devices requiring option settings.
