Agilent / Keysight N5244BM Active device characterization solution up to 43.5 GHz for 5G

The Keysight N5244BM is an active device characterization solution delivering S-parameter, noise figure, and harmonic measurements up to 43.5 GHz for 5G component validation. Built on the N5244B PNA-X network analyzer, this 4-port system combines industry-standard RF measurement with purpose-built software and calibration accessories for characterizing amplifiers, mixers, and transceivers in demanding 5G applications.

Technical Specifications

• Frequency Range: DC to 43.5 GHz


• Port Configuration: 4-port


• Dynamic Range: >130 dB


• S-Parameter Accuracy: <0.004 dB


• Noise Figure Accuracy: <0.1 dB


• Harmonic Measurement: <-65 dBc

Key Features The system integrates the N5244B PNA-X analyzer with calibration modules and measurement software. An N4693D 50 GHz ECal module enables fast, traceable calibration across the full frequency range. The U8487A 50 GHz USB power sensor provides independent verification of RF power delivery. A U9391F 50 GHz comb generator supports harmonic and intermodulation measurements. Four N9910X-714 2.4 mm test cables enable connection to DUT ports with minimal transition loss. An N1966A pulse input/output adapter extends measurement capability to pulsed RF environments. Included application software handles instrument control, result analysis, and advanced de-embedding workflows. Multiple specialized options on the N5244B - including 423, 020, 021, 022, and 029 - unlock source/load pull, nonlinear characterization, and pulsed RF measurement modes.
