PE1604

Overview

The PE1604 is a 50 Ohm SMA Bias Tee manufactured by Pasternack, designed for RF applications spanning 100 MHz to 6 GHz. It features an SMA female connector port and is rated for a maximum DC voltage of 50 Volts and a maximum current of 500 mA. The component provides 25 dB isolation between ports. This adapter facilitates the injection or extraction of DC bias signals onto RF lines while maintaining signal integrity within the specified frequency range.

Feature Summary

• Provides simultaneous DC biasing and RF signal transmission through a single path
• Features SMA female interface for standard coaxial connectivity
• Ensures signal isolation with a rating of 25 dB
• Supports continuous wave operation up to 500 mA and 50 V DC

Applications

• Biasing low-noise amplifiers (LNAs) in RF front-ends
• Powering active antennas requiring DC feed-through
• Test and measurement setups needing combined DC/RF signals
• Wireless communication system component integration

Procurement Notes

Verify that the required DC voltage does not exceed 50 Volts and the current remains within the 500 mA limit to prevent damage. Confirm that the operating frequency falls within the 100 MHz to 6 GHz range for optimal performance. Ensure SMA female mating compatibility with connected cables and modules. Check isolation requirements against the 25 dB specification for your specific application noise floor.

Selection Notes

Select this component when a compact solution is needed to combine DC power with RF signals in the UHF to lower microwave bands. It is suitable for systems where space constraints prohibit separate bias networks. Consider the 50 Ohm impedance match for standard RF infrastructure. Evaluate if the 6 GHz upper frequency limit meets the highest harmonic or fundamental frequency of the system.

Part Context

This part belongs to Pasternack's line of RF adapters and bias tees. It serves as a passive interconnect device allowing DC injection into RF paths. The design integrates standard SMA threading for robust mechanical connection. It is distinct from passive splitters or couplers by its specific function of separating or combining DC and RF domains.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Cross-referencing requires matching SMA female gender, 50 Ohm impedance, 100 MHz–6 GHz frequency range, and similar DC ratings.
