K&L Microwave's UHF Diplexer

K&L Microwave's UHF Diplexer

K&L is recognized by top-tier defense contractors and wireless infrastructure providers as a world leader in the design and manufacture of RF and microwave filters, duplexers, and integrated assemblies. K&L offers customers the most extensive range of filter-based products in the industry, spanning from 0.3 MHz to 94 GHz.

 Designed specifically for use in the UHF transponder aboard NASA's Curiosity rover, K&L's part number 7CZSP-397.5/442.5-O has been qualified for operation on the surface of Mars, as well as in the vacuum of space. The diplexer features less than 2 dB of insertion loss in its passbands of 390 to 405 MHz and 435 to 450 MHz with 90 dB of channel-to-channel isolation. Operational power of 60 W was tested without corona or multipaction from 1.5 x 10-5 to 12 Torr, simulating descent to and operation on the surface of Mars. Testing was done in a vacuum and in the presence of Mars gas. All qualification testing was performed in K&L's extensive environmental testing lab and confirmed at NASA's Jet Propulsion Laboratory.
