Hermetically sealable HTCC air-cavity QFN packages fit for 40GHz

November 14, 2013 // By Julien Happich
Barry Industries has unveiled high temperature co-fired ceramic (HTCC) hermetically sealable Quad-Flat-No-Lead (QFN) packages with air cavity for high frequency applications.

These QFN packages are available in six sizes from 3 to 8mm with standard JEDEC MO-220 footprints. They feature broadband low-loss transitions for superior performance over frequency. Maximum insertion loss is 0.5dB from DC to 18GHz, 1.5dB from 18 to 35GHz and 4dB from 35 to 40GHz. HTCC construction provides for enhanced mechanical strength and higher thermal conductivity compared to LTCC packages.  These extremely rugged packages are available with either a plain seal for epoxy or metallized grounded seal ring for solder lid attachment. Lids are available from the factory. Additional options include castellations and custom pin counts. Standard plating is gold over nickel.
