描述 Description

The MA4ST550 family of high Q Silicon Hyperabrupt Tuning Varactors is available in a series of low parasitic capacitance microwave packages or in chip form. The MA4ST550 series of diodes is available with junction capacitances of approximately 0.8 pF to 8.2 pF at -4 volts. These diodes have capacitance change ratios as high as 7:1.

特性 Features

● High Q

● Usable Capacitance Change of 7:1

● Low Reverse Leakage for Good Post Tuning Drift Characteristics

● Reproducible C-V Curves

Applications

The MA4ST550 series is appropriate for use in VCOs with frequencies within the range of approximately 1-14 GHz where a large capacitance change is required. These diodes are suited for VCOs in missile seekers, telecommunication systems and electronic warfare systems with critical post tuning drift specifications.
