描述 Description

Skyworks SKY77603 is a hybrid multimode, multiband Power Amplifier Module (PAM) that supports 2.5G / 3G and 4G handsets, and operates efficiently in GSM, EGPRS, EDGE, WCDMA, and LTE modes. The module is fully programmable through MIPI.

The PAM consists of a GSM850/EGSM900 PA block, a DCS1800/PCS1900 PA block, a separate WCDMA /LTE block for low and high bands, RF input/output ports internally matched to 50 Ω to reduce the number of external components, and a Multi-Function Control (MFC) block. A BiCMOS integrated circuit, using standard MIPI control, provides 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 6 x 8 x 0.9 mm, 38-pad MCM, SMT package which allows for a highly manufacturable, low-cost solution.

2.5G: The SKY77603 supports the GSM850, EGSM900, DCS1800, and PCS1900 bands as well as 2.5G Class12 Enhanced General Packet Radio Service (EGPRS) multi-slot operation and EDGE linear modulation.

In GSM mode, varying the VCC voltage maintains power control. In EDGE mode, varying the RF input drive level maintains power control. EDGE modulation covers both 8PSK and 16QAM.

3G: The SKY77603 supports WCDMA, High-Speed Downlink Packet Access (HSDPA), and High Speed Uplink Packet Access (HSUPA) modulation by utilizing a DC/DC converter. Varying the input power level maintains power control and adjusting VCC to maximize efficiency.

4G: The SKY77603 supports 1.4, 3, 5, 10, 15, 20 MHz channel bandwidths. Varying the input power level maintains power control and adjusting VCC to maximize efficiency. A supplied external VDAC supports multi-satellite LTE PAs.
