The SKY77652-11 from Skyworks is a multimode multiband Power Amplifier Module for 3G/4G handsets. It supports CDMA, WCDMA, TD-SCDMA, and LTE modes. This module is fully programmable through a Mobile Industry Processor Interface. The module consists of a WCDMA / LTE block for high and mid-bands, and a Multi-Function Control block. Its RF input/output ports internally matched to 50 ohms thereby reducing the number of external components required. The InGaP die and the silicon die and passive components are mounted on a multi-layer laminate substrate. This SMT module measures 3.65x 4.0x 0 .75mm. It can be used in Multiband 3G / LTE handsets and for LTE Carrier Aggregation/CDMA Bands BC1, BC4, BC6 and BC15.
