RFMD Amplifiers: Selection Guide, Benefits, and Manufacturers

rf amplifier rfmd radio frequency gain wireless

Introduction

RFMD amplifiers are known for delivering high efficiency and reliability in RF systems. Selecting the right amplifier involves understanding key parameters to ensure optimal signal performance. These amplifiers are available for both high frequency and low noise applications.

RF Micro Devices, Inc. (RFMD), which later merged with TriQuint Semiconductor to become Qorvo in 2015, developed several innovative RF amplifiers. As we know, an amplifier provides amplification to the signal to be transmitted; an RF amplifier specifically amplifies radio frequency signals.

RFMD offers various types of amplifiers tailored for different applications and needs. These include:

  • 3G power amplifiers
  • Gain modules
  • CATV amplifiers
  • High frequency and high reliability amplifiers
  • Linear amplifiers
  • Low noise amplifiers
  • Small cell power amplifiers

RFMD amplifiers are also commonly used in Wi-Fi, Zigbee, and other smart energy technologies.

RFMD Amplifier Selection Guide

When selecting an RFMD amplifier, consider the following specifications:

  • Frequency range of operation
  • Gain (dB)
  • Output 1 dB compression point (P1dB)
  • Saturated Power output (dBm)
  • Efficiency (%)
  • Output third order intercept point (OIP3 or TOIP)
  • Current consumption, Icc (mA)
  • Supply voltage, Vcc (V)

Advantages of RFMD Amplifiers

Here are some of the benefits of using RFMD amplifiers:

  1. Higher Efficiency: For example, the RF2172 amplifier.
  2. Integrated Power Control Loop: As seen in the RF3110 amplifier.
  3. Advanced GaAs HBT Technology: RFMD utilized gallium arsenide heterojunction bipolar transistor (GaAs HBT) technology in their amplifiers, providing high efficiency and linearity.
  4. Compact Design
  5. GaN Power Amplifiers: RFMD developed GaN power amplifiers capable of operating over wide bandwidths.
