SKY77619

SkyHi™ Multiband Multimode Power Amplifier Module for Quad-Band GSM / EDGE and Penta-Band (Bands I, II, IV, V, VIII) WCDMA/ HSDPA/ HSUPA/ HSPA+/ LTE


Please note: this product is being discontinued and is not recommended for new designs.

The SKY77619 is a hybrid, multimode, multiband Power Amplifier Module (PAM) that supports 2.5G and 3G/4G handsets and operates efficiently in GSM, EGPRS, EDGE, WCDMA, and LTE modes. The PAM consists of: a GSM 800 / EGSM 900 PA block, a DCS1800 / PCS1900 PA block, separate WCDMA blocks operating in low and high bands, a logic control block for multiple power control levels, and band enable functions in both cellular and UMTS. RF I/O ports are internally matched to 50 Q 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.

GSM/EDGE: The SKY77619 uses a new compact architecture supporting the GSM850, EGSM900, DCS1800 and PCS1900 bands. The PAM also supports 2.5G Class 12 Enhanced General Packet Radio Service (EGPRS) multislot operation and EDGE linear modulation.

WCDMA: The SKY77619 uses an enhanced architecture to support WCDMA, High-Speed Downlink Packet Access (HSDPA), and High-Speed Uplink Packet Access (HSUPA) and LTE modulations; cover multiple bands for 3GPP, including bands I, II, IV, V, and VIII; and operate at different power modes. The module is fully controllable via four logic lines and band-enable interfaces.

LTE: The SKY77619 meets spectral linearity requirements of LTE modulation with QPSK/16QAM up to 20 MHz bandwidth, including various resource block allocations, with good power-added efficiency
