PE8284

Overview

The PE8284 is an adjustable phase trimmer manufactured by Pasternack, designed for signal conditioning applications. It operates within a frequency range of 0 Hz to 18 GHz and maintains a 50 Ohm impedance. The device features SMA connectors and exhibits an insertion loss of 0.5 dB. It provides an adjustable phase shift capability of 15 degrees per GHz. The unit is housed in a stainless steel body with bulk packaging.

Feature Summary

• Adjustable phase trimming capability across a wide frequency spectrum
• Passivated stainless steel housing for durability
• SMA connector interface for standard RF integration

Applications

• Radar systems requiring precise phase alignment
• Signal conditioning in high-frequency test equipment
• RF circuit calibration and adjustment

Procurement Notes

Verify the specific datasheet version for the PE8284 to confirm current manufacturing status and detailed electrical tolerances. Ensure compatibility with SMA mating interfaces and verify that the 18 GHz upper frequency limit meets system requirements. Confirm housing dimensions fit within the intended mechanical enclosure constraints.

Selection Notes

Select the PE8284 when fixed-phase components do not meet system alignment needs. Its broad DC to 18 GHz range supports diverse microwave applications. The stainless steel construction offers environmental resilience. Verify that the 15 degrees per GHz adjustment rate aligns with the required phase resolution for the specific application.

Part Context

This component belongs to the Adjustable Phase Trimmers series from Pasternack. It serves as a passive signal conditioning element distinct from active amplifiers or switches. The design focuses on mechanical phase adjustment rather than electronic control, utilizing a physical trimmer mechanism housed in a robust metal casing for stable performance.
