Description

QFM4802 IC

The QFM4802

 is a high-performance Radio Frequency (RF) Integrated Circuit (IC) primarily designed by Qualcomm for use in mobile devices. It functions as a Power Amplifier (PA) within the RF Front-End (RFFE) subsystem of modern smartphones. 

Key Technical Description

  • Component Type: RF Power Amplifier (PA) IC.
  • Primary Application: Integrated into the RF signal chain of mobile phones to amplify high-frequency signals for transmission.
  • Subsystem Role: It often operates as a Legacy MMPA (Multi-Mode Power Amplifier) or part of the Sub-6GHz DL/UL (Downlink/Uplink) circuitry in 5G-capable hardware architectures.
  • Package Characteristics:
    • Designed for compact surface-mount integration, common in high-density mobile PCBs.
    • Approximate physical weight of 0.2 kg for bulk shipping units, with module dimensions typically around 2 × 2 × 2 cm for specialized carrier modules. 

Functionality in Mobile Systems

In a smartphone's hardware layout, the QFM4802 works alongside other RF components such as transceivers and low-noise amplifiers (LNAs) to manage signal strength and quality across various frequency bands. 

  • Efficiency: It is engineered to provide power-efficient amplification, which is critical for extending battery life in mobile devices while maintaining stable connectivity.
  • Compatibility: It is frequently found in motherboard designs for various global smartphone brands, often utilized in conjunction with Qualcomm's Snapdragon modem systems.
