The HP/Agilent 11636A is a precision 50 Ω power divider operating from DC to 18 GHz. It splits RF signals into two equal-amplitude, phase-coherent paths with symmetrical 6 dB division, making it suitable for calibration, network analysis, and broadband signal sampling in test systems. The device delivers exceptional output port symmetry and maintains stable attenuation across its frequency range with minimal temperature and power coefficient drift. No tuning or adjustments are required, and it functions equally well as a power combiner.
