Purchasing Resources for RF Transmitters/Receivers

RF Transmitters/Receivers

Control nearly any business electronic device with RF transmitters/receivers
By Apryl Beverly Radio Frequency (RF) transmitters/receivers are electronic devices that can be used to control or automate nearly any product that receives/transmits video, voice or data information. For example, retailers use RF transmitters as alternatives to barcodes in inventory management systems. RF receivers are also used in radios, security systems, cell phones, keyless entry gates and doors and many other eletronic products.
 

A basic understanding of the various modulation processes is necessary before choosing RF transmitters and receivers. Common modulation methods include amplitude modulation (AM), frequency modulation (FM) and phase modulation (PM). AM applies a varied voltage to the carrier. Alternatively, FM involves varying the frequency of the waveform. PM consists of delaying the natural flow of the alternating current waveform. Follow these steps to choose RF transmitters for your product:

1. Compare various types of RF transmitters and receivers and choose those that best fit your business needs.

2. Evaluate specialized services offered by RF transmitter design firms.

3. Shop online for various RF transmitter suppliers and find bargains on the devices you need.

Compare RF transmitters/receivers

Some RF receivers have visual or audible alarms or LED lights that indicate operation and signal reception. Other RF transmitter applications may require the use of additional products such as antennas, coaxial cables, connectors or ports. For outdoor use RF transmitters, you will need a strong, waterproof design. Wireless RF receivers and transmitters are useful in receiving data from remote locations without the need for wiring. Small RF transmitters and receivers work well for compact, portable devices.
