Description

The SMV2022 and SMV2023 devices are silicon hyperabrupt junction varactor diodes. The specified high capacitance ratio and low R S of these varactors make them attractive for low phase noise VCOs in wireless systems. Characteristic Value Reverse Voltage (VR) 22 V Forward Current (IF) 20 mA Power Dissipation (PD) 250 mW Storage Temperature (TST) -55°C to +150°C Operating Temperature (TOP) -55°C to +125°C Absolute Maximum Ratings CT @ 4 V CT @ 4 V C T @ 20 V C T @ 20 V Part Number (pF) (pF) (Ratio) Q @ 4 V Electrical Specifications at 25°C Reverse current IR (VR = 16 nA): 50 nA.
