The SKY58281-21 Front End Module (FEM) for LTE and NR is a new addition to our Sky5 portfolio of 5G Technology products. Key advances compared to previous generation dual band UHB modules are integrated MIMO Rx path and increased output power. The higher Pout enables PC2 support for n78 and n79. This versatile and fully matched FEM supports multiband 4G/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) module consists of PA blocks, input and output matching, a MIPI standard digital control block, single-ended filters, antenna and band select switches and low Noise amplifier (LNA).

Utilizing an enhanced architecture, the SKY58281-21 covers multiple bands and meets the spectral linearity and EVM requirements of CP-OFDM and DFTS-OFDM modulations up to 256 QAM. Output power is controlled by varying input power and adjusting VCC maximizes efficiency. Extremely low leakage current maximizes handset stand-by time.
