General Description

2-Way Wilkinson power dividers can be used for both in-phase power splitting and power combining applications. These power dividers feature the lowest insertion loss (ideally 3 dB splitting loss), excellent amplitude and phase balance, and high isolation across the entire operating band. High isolation can be critically important for power combining applications, such as when performing accurate intermodulation distortion (IMD) tests.

Features

  • 5 to 35 GHz In-phase Power Splitting
  • 1.5 dB Typical Insertion Loss
  • 18 dB Typical Output to Output Isolation
  • Outstanding Amplitude and Phase Balance
  • Surface Mount Package
