Device Overview

General Description

The BT-0034SMG is a packaged bias tee featuring excellent insertion loss and superior isolations over a broad 500 kHz to 34 GHz bandwidth. Tight fabrication tolerances allow for low unit to unit variation enabling accurate simulations using the provided s3p file taken from measured production units. The bias tee is available in a compact package and is suitable for applications such as amplifier biasing, diode biasing and DC level shifting.
