Chip On Board Mixer Quads Features High Volume Automatic Assembly For Microwave MIC Assembly and Automated High Volume Manufacturing Mechanically Rugged Design 100% DC Tested Three Barrier Heights for Customized Mixer Performance Description Alpha's ceramic Chip on Board (COB) mixer quads are designed for high performance RF and microwave receiver applications. These devices utilize Alpha's advanced silicon beamless Schottky technology, combined with precision ceramic COB assembly techniques, to achieve a high degree of device reliability in commercial applications. Performance to 10 GHz is available with the ring quads in the 106 package, which employs via hole technology resulting in metalized contacts on the bottom side and eliminating the need for wire bonds to topside contacts.
