Sky5 Front-End Module for 4G and 5G Applications: SKY58277-31 Datasheet

The SKY58277-31 Front-End Module (FEM) for LTE and NR is a new addition to the Skyworks Sky5 portfolio of 5G technology products. This versatile and fully matched FEM supports ultra-high band 4G/5G and LTE/NR applications.

The device is packaged in a single 5.0 mm x 3.0 mm x 0.7 mm (max) form factor. The 30-pad surface mount (SMT) module consists of PA blocks, input and output ports matched to 50 ohms, a MIPI standard digital control block, filter, antenna and Tx-Rx switches, and low noise amplifier (LNA).

Utilizing an enhanced architecture, the SKY58277-31 covers multiple bands 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 to maximize efficiency. Extremely low leakage current maximizes handset stand-by time.
