SKY74068-21 - Dual-Band Transmitter

Description

The SKY74068-21 transmitter is a highly integrated device for dual-band Code Division Multiple Access (CDMA) femtocells.

The SKY74068-21 supports femtocells in the cellular CDMA and Personal Communications System (PCS) modes.

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 .
  • Single-ended PCS driver output matched to 50 .
  • Transmit powe.

DATA SHEET SKY74068-21: Dual-Band Transmitter for CDMA and PCS Femtocell Applications Applications  Dual-band femtocells Description The SKY74068-21 transmitter is a highly integrated device for dual-band Code Division Multiple Access (CDMA) femtocells. The SKY74068-21 supports femtocells in the cellular CDMA and Personal Communications System (PCS) modes. The device requires a minimum number of external components to complete 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).
