Front-End Module for LTE and NR

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
