Schottky Barrier Beam Lead and Packaged Ring Quads Features Small Physical Size for Microstrip Mounting High Reliability Closely Matched Junctions for High Isolation High Barriers for LO Power Levels up to +27 dBm Minimum Parasitics for Broadband Designs Description Single Barrier Ring Quads Each Schottky barrier dicde quad consists of four closely matched diodes connected in a ring configuration. The four diedes are formed monolithically to assure close matching of electrical characteristics: capacitance, forward voltage and series resistance. The beam lead construction assures minimum junction capacitance, minimum con- nection lead inductance and permits the interconnection of the diodes into rings at the wafer level. Dual Barrier Ring Quads Each dual barrier ring quad consists of eight Schottky diodes connected in a ring configuration. Each arm of the quad consists of two high barrier Schottky diodes. The structure is formed monclithically to assure close match- ing of electrical characteristics. They are available in the low cost 1008 package. Medium Barrier Cross-Over Quads M/A-COMs ring quads are available in beam lead form and five stripline case styles which are compatible with microstrip assembly techniques. The 226 case style is her- metically sealed and should be used in either harsh envi- ronments or high reliability military systems. The 228 case style is a low-cost package of similar size to the 226 case style. Case style 227 is suggested for either high fre- quency or wide bandwidth applications. Case style 963 has the lowest parasitics and is suggested for widest bandwidth applications. Case style 1008 is a low cost moderate frequency package used in many double bal- anced mixers through 2 GHz. Specifications Subject to Change Without Notice. M/A-COM, Inc.
