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 ultrahigh
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.
