The SKY77916-11, often referred to simply as the 77916-11, is a high-performance Transmit/Receive Front-End Module (FEM) developed by Skyworks Solutions.1 It is a critical component in the radio frequency (RF) architecture of modern smartphones, specifically designed to handle multi-mode and multi-band cellular communications.2
The module is part of the SkyLiTE™ family, which aims to provide a scalable and compact solution for global LTE (4G) and 3G/2G connectivity.3 Below is a detailed technical breakdown of its specifications and functionality.
Technical Overview
The SKY77916-11 serves as a bridge between the phone’s internal transceiver and the external antenna.4 Its primary role is to amplify outbound signals (transmit) and route inbound signals (receive) across a variety of network standards, including GSM, GPRS, EDGE, TD-SCDMA, and TDD-LTE.

Core Features and Functionality
1. Multi-Band Amplification
The IC houses two distinct Power Amplifier (PA) blocks:
-
Low Band (LB): Optimized for GSM850 and GSM900 bands.5
-
High Band (HB): Supports DCS1800, PCS1900, TD-SCDMA (Bands 34/39), and TDD-LTE (Band 39).6
2. Advanced Switching Network
With 14 linear TRx ports, the IC can manage a complex array of antennas and frequency filters.7 It includes a high-linearity, low-loss switch that ensures signal integrity is maintained even in congested spectrums.8 The switch features 0 volts DC offset, which removes the need for bulky external DC blocking capacitors, saving valuable space on the phone’s Printed Circuit Board (PCB).9
3. MIPI® RFFE Control10
Modern smartphones require lightning-fast switching between bands and modes. The 77916-11 uses the industry-standard MIPI® RFFE interface.11 This allows the phone’s central processor to precisely control the module’s bias, band selection, and power modes through digital commands, significantly improving power efficiency and performance.
4. Power Management and Protection
-
FB-iPAC: Skyworks’ “Finger-Based Integrated Power Amplifier Control” technology helps minimize output power variation caused by antenna mismatch.12
-
Protection Circuits: It includes built-in over-voltage and over-current protection to prevent damage during power spikes or antenna failures.13
-
Leakage Control: The design focuses on extremely low leakage current, which is vital for maximizing the handset’s standby battery life.14
Common Applications
This IC is widely used in mid-range and budget-friendly smartphones that utilize Qualcomm or MediaTek chipsets.15 You will commonly find it in devices from:
-
Xiaomi/Redmi: (e.g., Redmi Note series)16
-
Samsung Galaxy: (Specific A and J series models)
-
Lenovo, HTC, and Infinix: Various 4G-enabled models.17
Note for Technicians: When replacing this IC, professional BGA (Ball Grid Array) soldering tools are required.18 Because it is an RF component, improper installation or “cold joints” will result in “No Service” or weak signal issues.
