RF Transmitter: Selection Guide, Benefits & Leading Manufacturers

Introduction: RF transmitters send radio frequency signals over the air. Choosing the right transmitter depends on frequency range, power output and modulation type.

What is RF transmitter:
The RF device which does transmission of radio frequency signal is known as RF transmitter. The RF device which receives the RF signal is known as RF receiver. The device which houses both RF Transmitter and RF receiver is known as RF Transceiver.
Refer RF transceiver basics>> for more information.

There are two main components in the RF transmitter viz. modulator and up converter. The modulator part does modulation of the raw information to generate modulated output. There are two main types of modulation analog modulation and digital modulation. The up converter does up conversion of the lower frequency modulated signal to generate high frequency output in order to have feasible transmission over the air with the help of antenna. Power Amplifier (PA) is needed to amplify the signal before transmission to compensate for the power losses as per RF link budget.

Selection Guide

• Frequency range to ensure compatibility with your target communication band.
• Output power to achieve the desired transmission range while avoiding distortion.
• Modulation type to match the system’s requirements (e.g., AM, FM, QAM).
• Efficiency of the transmitter is critical for minimizing power consumption, especially in battery operated devices.
• Linearity and signal fidelity to prevent signal distortion and ensure clear transmission.
• The size and form factor for space constrained applications.
• Ensure the transmitter provides robust thermal management to handle high power operation.

Advantages of RF Transmitter

Following are some of the benefits of RF Transmitter.
1. RF transmitters enable wireless communication over long distances by efficiently transmitting high frequency signals.
