Overview

Quadrature former (QF) generate differential output signals with phase shift of 90° for each of 4 channel, coherent to input signal. QF has two inputs and works with one differential or two independent signals. Output phase adjustment for each channel gives minimal phase error

Key features

  • AMS035 BiCMOS 0.35 um
  • 4 independent outputs
  • Works with two input signal with different signals for output 1,2 and 3,4 respectively
  • Up to 4 outputs with one input signal
  • Adjustable output phase in range ±4.5° for each channel
