Multi-Mode/Multi-Band Power Amplifier Module: SKY77604-11

This power amplifier module consists of a GSM800/EGSM900 PA block, a DCS1800/PCS1900 PA block, separate WCDMA blocks 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. All of this is encapsulated in a 6 mm x 8 mm, 34-pad MCM, Surface-Mounted Technology (SMT) package, resulting in a highly manufacturable and low cost solution.  

The SKY77604-11 Multi-Mode/Multi-Band Power Amplifier Module is ideal for applications involving quad-band cellular handsets, multiband 3G handsets, and WCDMA/HSDPA/HSUPA/HSPA+ modulated handsets (Bands I, II, IV, IX, X, V, VIII).
