STW81101 - Multi-band RF frequency synthesizer

General Description

The STMicroelectronics STW81101 is an integrated RF synthesizer with voltage controlled oscillators (VCOs).

Showing high performance, high integration, low power, and multi-band performances, STW81101 is a low-cost one-chip alternative to discrete PLL and VCO solutions.

Key Features

  • Integer-N frequency synthesizer.
  • Dual differential integrated VCOs with automatic center frequency calibration:.
  • 3300 - 3900 MHz (direct output).
  • 3800 - 4400 MHz (direct output).
  • 1650 - 1950 MHz (internal divider by 2).
  • 1900 - 2200 MHz (internal divider by 2).
  • 825 - 975 MHz (internal divider by 4).
  • 950 - 1100 MHz (internal divider by 4).
  • Excellent integrated phase noise.
  • Fast lock time: 150 µs.
  • Dual modulus programma.
