SKY74068-11 Datasheet Dual-mode Transmitter

Manufacturer: Skyworks Solutions

Overview: PRODUCT SUMMARY SKY74068-11: Dual-Band, Dual-Mode Transmitter for CDMA, AMPS, and PCS Mobile Handset Applications Applications • Dual-band, dual-mode handsets • Cellular and PCS band phones − CDMA and AMPS modes in the.

General Description

The SKY74068-11 transmitter is a highly integrated device for dual-band Code Division Multiple Access (CDMA) handsets in the cellular CDMA, Advanced Mobile Phone System (AMPS), and Personal munications System (PCS) modes.

The device requires a minimum number of external ponents to plete a CDMA radio subsystem.

Included on-chip are the baseband filter, direct upconversion In-Phase and Quadrature (I/Q) mixers, variable gain power amplifier (PA) drivers, a fully integrated Voltage Controlled Oscillator (VCO) with Local Oscillator (LO) generation blocks, and a dual-mode fractional-N/integer-N Phase Locked Loop (PLL).

Key Features

  • Low power consumption in all operating modes.
  • Direct upconversion architecture.
  • Device controlled using a three-wire read/write serial bus interface with independent supply voltage.
  • Baseband RC filter to reject receive band noise.
  • Fully integrated VCO with auto-tuning.
  • Dual-mode fractional-N/integer-N PLL.
  • Variable gain PA drivers.
  • Differential cellular driver output matched to 200 Ω.
  • Single-ended PCS driver output.
