4028A

RF Directional Thruline Precision Power Sensors

4028 Series

Bird’s® 4028 Series Power Sensors are a family of high accuracy sensors for use in high power LCD, TFT and Solar processing and
other precision high power applications. Intended for use with the industry standard Bird Precision Laboratory Power Meter
Model 4421, these products can provide a threefold improvement in long-term unit-to-unit accuracy.

Achieve tighter, more consistent RF power measurements for improved yield. 

±2% accuracy at specified calibration frequencies and power levels.

Direct, plug-in operation with the industry standard Bird Model 4421 RF Power Meter.

Multiple sensors provide for measurement of 1 kW to 25 kW over a 250 kHz to 30 MHz frequency range.

PROBLEMS/SOLUTIONS

Very high power RF measurements required

Measures power levels up to 50kW

Need very high degree of accuracy

Capable of 2% accuracy

Require custom connectors

4028A Series sensor can be configured with a wide range of connectors.

APPLICATIONS
Periodically, power delivery systems used in high power LCD, TTA and Solar processes, as well as other precision applications, must be calibrated against an accurate RF power standard. This calibration is used to correct for any drift that may occur in the system. Integrating a 4028 Series Power sensor in your calibration process may improve accuracy and long-term repeatability that can yield significant improvements on your process yields.
