NR Power Amplifier Module for ENDC Applications

The SKY77652-31 is a Power Amplifier Module (PAM) that supports 5G handsets and operates efficiently in NR mode when ENDC is required. The PAM consists of PA blocks for mid-bands and high-bands, a logic control block for multiple power control levels, and band enable functions. RF I/O ports are internally matched to 50 Ω to minimize the number of external components. Extremely low leakage current maximizes handset standby time.

The InGaP/GaAs die and passive components are mounted on a multi-layer laminate substrate and the assembly encapsulated in plastic over-mold.


The SKY77652-31 meets spectral linearity requirements of NR modulation with DFT and CP OFDM modulations with up to 256 QAM constellations. The PAM supports various resource block allocations within 3GPP defined transmission bandwidth with good power-added efficiency.
