SKY5A3300

Sky5® Front-End Module for LTE and NR

The SKY5A3300 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.

A higher Pout enables PC2 support for n78. This versatile and fully matched FEM supports multiband 4G/5G and LTE/NR applications.

Using an enhanced architecture, the device covers multiple bands and meets the spectral linearity and error vector magnitude (EVM) requirements of CP-OFDM and DFTS-OFDM modulations up to 256 QAM.

Output power is controlled by varying input power and adjusting VCC to maximize efficiency. Extremely low leakage current maximizes standby time. 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 LNA.
