Agilent/Keysight 11636C

The Keysight 11636C is a three-port, 50 ohm power divider engineered for precision RF and microwave applications spanning DC to 50 GHz. Operating bidirectionally, it functions equally well as a power combiner, with any port serving as input or output. The device delivers exceptional amplitude and phase tracking across its full frequency range, making it ideal for accurate power division, signal routing, and network analyzer-based fault location measurements.
