- Hand-held radio transceivers operate on narrow band frequencies.Radio waves are the part of the electromagnetic spectrum with the longest wavelengths. A transceiver is a type of radio equipment that can both transmit and receive this long wavelength radiation to communicate with other people or share to data. Transceivers are more common than you might think. Amateur radio hobbyists and CB enthusiasts talk to one another using transceivers. A walkie-talkie is a radio transceiver and so is your cell phone. Even the wireless router connected to many computers is a type of radio transceiver
- The Federal Communications Commission regulates the frequencies that different types of communications equipment may transmit and receive. Transceivers of different types are built so that they transmit and receive signals at the range of frequencies allocated for that type of equipment. Frequency ranges are allocated for mobile phone, 2-way radio, citizens band and amateur radio transceivers. According to the National Association for Amateur Radio, amateur radio transceivers operate at set wavelengths from 23 centimeters up to 160 meters. Frequency availability is determined by the class of license the operator holds
- The transmitter inside each type of transceiver is designed to operate at a set power level. The output power is measured in watts. A walkie-talkie type hand held transceiver will have a power out put of around 5 watts. This means that the transmitter inside sends a signal at 5 watts of power through the antenna. Base transceiver units and CB radio transceivers operate at higher power levels. The instruction manual for a VHF/HF transceiver provided to students by the University of Indiana describes the transmitter power of the base unit to be between 5 and 100 watts when transmitting an FM signal and between 5 and 40 watts for AM signal transmission
Software Defined Radio Transceivers
- ICs and software process the signal in SDR radio transceivers.Software Defined Radio transceivers bring amateur radio into the digital domain by combining radio with computers. A SDR transceiver converts the analog radio signal to a digital signal and uses software to process and filter the signal for transmission. SDR transceiver software is configurable to allow the transceiver to operate in the narrow band unlicensed frequencies or in the licensed amateur radio bands. According to the EURASIP Journal on Wireless Communications and Networking, the transceiver sends the input signal through the processor where it is filtered and optimized by the software. The signal is then passed through a converter circuit that changes it from an analog signal to a digital signal. It is then broadcast through the antenna. The type of signal that is broadcast is determined by wireless transmission standards issued by the FCC

- What is the difference between the active and passive currents in transmitter?
The difference between active and passive transmitter currents is pretty simple when dealing with communications technology.
With active transmitter currents requests are being sent out (or transmitted) for information and monitoring.
With passive transmitter currents it only reacts when information is directed AT it.
Active is looking at the clock waiting for the alarm to go off, and passive is laying there waiting for it to go off on it's own.
- What's structure of this active video transmitter?
4 channel active video balun transmitter, with adjustable gain control for each camera. 8x Push-pin terminal or RJ-45 to 4x BNC, transmit security surveillance camera video 4 channel upto up to 3,000ft when used with any passive transciever. Full-motion color CCTV video at distances up to 8,000ft when used with any active receiver. Use with low cost unshielded twisted pair / UTP wire or CAT5 cable.
- Does active transmitter have more advantages compared with passive transmitter?
Yes, cooperating with active transmitter can transmit the color video signal 1600m away and with passive transmitter can transmit the color video signal 400m away. Best choice for CCTV signal transmission.
