LMH ENDC Multimode/Multiband Power Amplifier Module

The SKY58253-11 supports 5G handsets and operates in NR mode when ENDC is required. The PAM consists of PA blocks for Low-bands, 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 PA die, CMOS controller, and SOI switch die and passive components are mounted on a multi-layer laminate substrate and assembly encapsulated in plastic overmold and coated with conformal shielding.


The SKY58253-11 meets spectral linearity requirements of NR modulation with DFT and CP OFDM modulations with up to 256 QAM constellations. The PAM supports resource block allocations within 3GPP defined transmission bandwidth with good poweradded efficiency.
