Data Sheets

Features and Description

– Exceptional flatness: +1 dB

– Extremely broadband: 0.01 ‑ 26.5 GHz

– Compact size

– Environmentally rugged

 

The Keysight Technologies, Inc. 83036C is a broadband microwave power sampler which operates in the same fashion as a traditional coupler‑detector combination, but with improved frequency response and much smaller size. The directional detector is designed to perform over the 10 MHz to 26.5 GHz frequency band with ±1.0 dB of output voltage variation at room temperature. The directional detector is capable of operating with greater than one watt of input power when terminated with well-matched source and load impedance. An input power derating curve is provided for calculating the maximum input power for other source and load impedance.

 

The 83036C is comprised of a resistive bridge and a broadband planar‑doped barrier (PDB) diode. The circuit is shown in Figure 1. The bridge is manufactured by depositing thin film resistors directly onto GaAs substrate material. The use of a resistive bridge as the signal-sampling device makes possible the extremely broadband device response.
