Device Overview

General Description

The BTM-0026PSM-2 is a packaged miniature bias tee featuring excellent 0.4 dB insertion loss and superior 25 dB isolations over a broad 10 MHz to 26 GHz bandwidth. The BTM-0026PSM-2 works well for K-Band applications. The BTM-0026PSM-2 is available in a compact 2.25 x 3.7 mm surface mount package or as a connectorized evaluation board. Tight fabrication tolerances allow for low unit to unit variation enabling accurate simulations using the provided s3p file taken from measured production units, making it an excellent alternative to uncharacterized, untested bias tees built with off-the-shelf inductors and capacitors.
