PE1619

Overview

The Pasternack PE1619 is a general-purpose RF IC bias tee designed for frequencies ranging from 0.03 MHz to 70 GHz. It utilizes SMA connectors on all ports and features a 1.85mm internal design. The component is rated for a maximum DC current of 500 mA and a voltage rating of 25 Volts DC. It operates within an ambient temperature range of -40°C to +85°C and maintains a VSWR of 1.3:1 or less across its frequency spectrum. The unit provides isolation greater than 40 dB at 10 GHz.

Feature Summary

• Provides simultaneous DC power injection and RF signal transmission through a single port configuration
• Supports ultra-wideband operation extending up to 70 GHz with low insertion loss
• Features SMA connectors on all ports for compatibility with standard laboratory testing equipment

Applications

• Biasing RF integrated circuits in test and measurement setups
• Characterizing high-frequency semiconductor devices and amplifiers
• Integrating into automated test equipment requiring combined DC and RF paths

Procurement Notes

Verify the specific connector gender and pin configuration against your system requirements before ordering. Confirm that the 500 mA current limit and 25 VDC voltage rating are sufficient for your target device's biasing needs. Ensure the SMA interface matches the mating components in your existing RF chain to maintain signal integrity.

Selection Notes

Select this model when a wide bandwidth up to 70 GHz is required for biasing applications. Consider the SMA interface compatibility if integrating with standard RF test gear. Evaluate the thermal performance if continuous operation near the maximum current rating is anticipated, as heat dissipation may affect long-term stability.

Part Context

This component belongs to Pasternack's family of RF bias tees, which are essential passive accessories for RF engineering. Bias tees allow engineers to power active components without disrupting the RF signal path. The PE1619 specifically targets high-frequency applications where standard bias tees might suffer from excessive loss or poor isolation at millimeter-wave frequencies.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. When replacing, ensure the new component matches the 70 GHz upper frequency limit, SMA connector type, and 500 mA current rating to maintain system performance.
