SKY58281-21中文资料Sky5® Front End Module for LTE and NR数据手册Skyworks规格书

描述 Description

The SKY58281-21 Front End Module (FEM) for LTE andNR is a new addition to our Sky5 portfolio of 5GTechnology products. Key advances compared toprevious generation dual band UHB modules areintegrated MIMO Rx path and increased output power.The higher Pout enables PC2 support for n78 and n79.This versatile and fully matched FEM supports multiband4G/5G and LTE/NR applications.

Packaged in a single 4.5 mm x 5.5 mm x 0.7 mm (Max.)form factor, the 42-pad surface mount (SMT) moduleconsists of PA blocks, input and output matching, aMIPI standard digital control block, single-endedfilters, antenna and band select switches and lowNoise amplifier (LNA).

Utilizing an enhanced architecture, the SKY58281-21covers multiple bands and meets the spectral linearityand EVM requirements of CP-OFDM and DFTS-OFDMmodulations up to 256 QAM. Output power iscontrolled by varying input power and adjusting VCCmaximizes efficiency. Extremely low leakage currentmaximizes handset stand-by time.
