Agilent 11667L Power Splitter DC-2 GHz, BNC, 50 ohm Technical Overview
The Agilent 11667L is a 50 ohm two-resistor type power splitter with BNC connectors. The 11667L provides exceptional amplitude and phase tracking for highly accurate power splitting. Offering excellent output power symmetry between the two output ports, the 11667L is recommended for applications that require external source leveling and ratio measurements by using the E5061B network analyzer (at its gain-phase test port), and for other legacy network/ gain-phase analyzers that do not have built-in power splitters or directional bridges.
Key Features • Excellent amplitude (0.2 dB) and phase tracking (±3°) ensures highly accurate power splitting • Low SWR minimizes measurement uncertainty
Application examples Network Measurements Transmission coefficient measurements for 2-port devices
Milliohm impedance measurements with shunt-thru method (DC-DC converters, large bypass capacitors)
