53B53B53B54B54B53BDescription
The SKY58277-31 Front-End Module (FEM) for LTE and NR is a
new addition to the Skyworks Sky5 portfolio of 5G technology
products. The device is packaged in a single 5.0 mm x 3.0 mm x
0.7 mm (max) form factor. This versatile and fully matched FEM
supports ultra-high band 4G/5G and LTE/NR applications.
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.
