NR Power Amplifier Module for ENDC Applications

The Skyworks SKY77651-41 Power Amplifier Module (PAM) supports 5G handsets for ENDC operation. The module is fully programmable through a Mobile Industry Processor Interface (MIPI®).

The PAM consists of a 4G/5G blocks for low band, a Multi-Function Control (MFC) block and RF input/ output ports internally matched to 50 Ω to reduce the number of external components. A CMOS integrated circuit uses standard MIPI controls to provide the internal MFC interface and operation. Extremely low leakage current maximizes handset standby time.

The InGaP die and the silicon die and passive components are mounted on a multi-layer laminate substrate. The assembly is encapsulated in a 2.8 mm x 4.0 mm x 0.75 mm, 24-pad MCM, SMT package which allows for a highly manufacturable, low cost solution.


The SKY77651-41 supports 1.4, 3, 5, 10, 15, 20 MHz channel bandwidths. Output power is controlled by varying the input power and VCC is adjusted using a DCDC converter to maximize efficiency for each power level.


The SKY77651-41 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.
