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 50Ω 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 overmold.
5G NR
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. Figure 1
shows the SKY77652-31 functional block diagram.
