PE8246

Overview

The Pasternack PE8246 is a 50 Ohm SMA to SMA adjustable phase trimmer designed for RF applications requiring precise phase matching between cables. It operates from DC to 12 GHz with an adjustable phase shift of 60 degrees per GHz. The device features field-replaceable connectors and supports continuous phase adjustment, making it suitable for systems needing fine-tuned signal alignment.

Feature Summary

• Provides continuous phase adjustment across the operating frequency range
• Designed for precise phase matching between RF cable paths
• Features SMA female connectors on both input and output ports

Applications

• RF system phase calibration
• Antenna array beamforming adjustments
• Test and measurement equipment phase alignment

Procurement Notes

Verify the specific datasheet version for the PE8246 to confirm the exact frequency range and phase adjustment specifications. Ensure compatibility with 50 Ohm systems and SMA connector types. Check for RoHS compliance status if required by your manufacturing standards. Confirm that the adjustable phase mechanism meets the mechanical constraints of your assembly environment.

Selection Notes

Select the PE8246 when precise, continuous phase trimming is required in the DC to 12 GHz range. It is ideal for applications where fixed phase shifters lack the necessary flexibility. Consider the physical size and mounting requirements for integration into existing RF chains. Ensure that the 60 deg/GHz adjustment rate aligns with the system's phase resolution needs.

Part Context

This component belongs to Pasternack's line of adjustable phase trimmers, which are used for fine-tuning phase differences in RF circuits. These devices are distinct from digital or stepped phase shifters, offering analog control for high-precision applications. The PE8246 specifically targets users needing reliable, low-loss phase adjustment in microwave systems.

Replacement Considerations

The PE82P5006 is a similar adjustable phase shifter but operates from DC to 8 GHz. Verify if the lower frequency limit of the PE82P5006 meets the application requirements. Both devices offer SMA connectors and adjustable phase capabilities, but the frequency range difference is critical for selection.
