General Description

The MTPX-00001CSP3 is a MMIC surface mount low pass, band pass, and high pass triplexer/reflectionless filter featuring 10.12 GHz and 18.16 GHz crossover frequencies. Passive MMIC technology allows production of smaller filter constructions that replace larger form factor circuit board constructions. Tight fabrication tolerances allow for less unit-to-unit variation than traditional filter technologies. The MTPX-00001CSP3 is available as a 3.5 x 3.5 mm CSP3. Low unit-to-unit variation allows for accurate simulations using the provided S-parameter file taken from measured production units.

Features

  • Low Insertion Loss, ≤ 2.3 dB Typical
  • Crossover Points, 10.1 GHz and 18.2
  • Excellent Return Losses, > 19 dB Typical
  • High Band to Band Isolation, 37 dB Typical
