RF Amplifier Selection Guide: Benefits and Manufacturers

RF amplifiers boost signal strength for better transmission and reception. Choosing the right amplifier requires an understanding of gain, bandwidth and noise figure. This guide explores selection criteria, benefits and top manufacturers.

RF power amplifiers are used in RF, microwave, satellite, and wireless applications, covering various standards including WiMAX, WLAN, WIFI, LTE, CDMA/EVDO, EDGE, WCDMA/HSPA, etc.

Selection Guide

The following specifications of an RF amplifier need to be evaluated before purchase:

• Frequency Range
• Gain
• P1dB (1 dB compression point)
• Supply voltage
• 3rd order intercept point
• RS-485/serial communication
• Power Added Efficiency
• VSWR
• Connectors (in the case of module/equipment)
• Heat sink (in the case of module/equipment)

Advantages of RF Amplifier

Following are some of the benefits of using an RF amplifier:

1. Boosts weak RF signals to ensure reliable transmission and reception over long distances.
2. It improves SNR (Signal to Noise Ratio), which enhances the quality of received signals.
3. It supports a wideband frequency range, making it suitable for multi-band applications.
4. Optimizes power output for efficient transmission, which is crucial for RF communication, broadcasting, and satellite systems.
