Marki's MMIC Filters are Hot, Hot, Hot!

Marki - Banner 2

Marki’s MMIC Filters offer excellent repeatability, smaller form-factors, and higher operating frequencies with rapid development, reasonable prices, and first-pass design success. As noted in Doug Jorgesen and Christopher Marki’s technical article, MMIC Filters’ Time Has Come, GaAs MMIC filters offer the best combination of performance, cost, and consistency – recent testing further indicates that these filters maintain consistency with low variability over temperature and high power handling capabilities.

We’re often asked, “can these filters handle at least 1W?”, but we’ll do you one better and find the max power handling for our current MMIC filters. This experiment explores the MFBA and MFBC filter families to demonstrate how extreme power and temperature conditions affect different filter topologies.
