Product Summary

The QSC1100 amplifier enables CDMA2000 handsets for emerging markets. In addition to supporting features such as downloadable polyphonic ringtones and color displays, the QSC1100 solution doubles talk time compared to currently available CDMA2000 handsets. The solution integration of baseband modem, RF transceiver, power management and system memory into a single chip reduces the number of discrete components required, reduces bill-of-materials costs and delivers board-area savings of more than 50%. The QSC1100 solution offers a wide range of features to deliver a superior user experience, including voice/SMS and support for downloadable polyphonic ringtones and wallpapers, 65 nm process technology and multiple-frequency operation, including 450 MHz, 800 MHz, 1900 MHz and 2100 MHz.
