PRELIMINARY DATA SHEET
SKY5®-8254-11 Front-End Module for LTE and NR Applications Multi-band 4G / 5G handsets - Band 41 and n41
Features Fully Baseband Agnostic Design
Full Power APT support without DPD
HB S-PAD covering Band n41
MIPI® v2.1 compliant 52 MHz RFFE bus
High performance ET/APT PA core
50 ohm input/output impedance with internal DC-blocking
Continuous bias control via RFFE interface
Low leakage current in power-down mode
Features Integrated Tx-Rx switches
Small, low profile package - 3.0 mm x 5.0 mm x 0.7 mm (Max.) - 30-pad surface mount (SMT) configuration
Description SKY58254-11 is a recent addition to our Sky5 portfolio of 5G Technology products. Packaged in a single 3.0 mm x 5.0 mm x 0.7 mm (Max.) form factor, this versatile and fully matched Front-End Module (FEM) supports band 41 5G and NR applications. The 30-pad surface mount (SMT) module consists of PA blocks, input/output impedance matched to 50 ohms, an MIPI standard digital control block, single-ended filters, Tx-Rx switches and forward/reverse coupler.
Utilizing an enhanced architecture, SKY58254-11 covers full Band 41 and meets the spectral linearity requirements of CP-OFDM and DFTS-OFDM modulations with up to 100 MHz bandwidth and up to 273 resource block allocations. Output power is controlled by varying input power and adjusting VCC maximizes efficiency. Extremely low leakage current maximizes handset stand-by time

Package Handling Information Because the device package is sensitive to moisture absorption, it is baked and vacuum packed before shipping. Instructions on the shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly.
The SKY58254-11 is rated to Moisture Sensitivity Level 3 (MSL3) at 260 °C. It can be used for lead or lead–free soldering. For additional information, refer to Skyworks Application Note, PCB Design and SMT Assembly/Rework Guidelines for MCM–L package, Document Number 101752.
Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. Refer to Standard SMT Reflow Profile JEDEC Standard J–STD–020.
Production quantities of this product are shipped in a standard tape and reel format.
