PE1639

Overview

The Pasternack PE1639 is a broadband bias tee designed for signal conditioning applications. It operates within a frequency range of 50 kHz to 26 GHz and features an SMA male input connector. The device is rated for a maximum voltage of 25 volts and a maximum current of 750 mA. Insertion loss varies between 1.4 dB and 3 dB across the operational bandwidth. This three-port network allows for the adjustment of DC bias points in electrical components without affecting RF signals.

Feature Summary

• Provides broadband signal conditioning from 50 kHz to 26 GHz
• Enables DC bias injection via a dedicated port while maintaining RF integrity
• Features SMA male input connector for standard integration

Applications

• Adjusting DC bias points of electrical components without affecting other circuit elements
• RF signal conditioning in test and measurement setups
• Biasing active RF components such as amplifiers or mixers

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer specifications may be updated. Confirm that the SMA male input configuration matches your system requirements. Ensure the 25 V and 750 mA ratings are sufficient for your intended DC bias application. Check lead times with authorized distributors, as they can vary significantly based on stock levels and manufacturing schedules.

Selection Notes

Select the PE1639 when a wideband frequency response up to 26 GHz is required for biasing applications. Consider the insertion loss range of 1.4 to 3 dB when evaluating signal integrity impact. Ensure compatibility with SMA connectors on both the RF and DC ports if applicable. Verify that the voltage and current limits meet the specific needs of the component being biased.

Part Context

The PE1639 belongs to Pasternack's line of signal conditioning components, specifically bias tees. These devices are essential for integrating DC power into RF circuits without disrupting high-frequency signal transmission. Unlike passive adapters, bias tees actively manage the separation and combination of DC and RF energy, making them critical in complex RF systems requiring precise bias control.
