Silicon Hyperabrupt Junction Varactor Diode SKYWORKS SMV1237-001LF Rated for 260 Degree Celsius MSL1
Product Overview
The Skyworks SMV123x series are silicon hyperabrupt junction varactor diodes designed for low tuning voltage Voltage Controlled Oscillators (VCOs). These varactors feature low series resistance, making them suitable for high-Q resonators in wireless system VCOs operating at frequencies over 10 GHz. They are characterized for capacitance and resistance over temperature and are rated MSL1, 260 C per JEDEC J-STD-020. Skyworks Green products are compliant with applicable legislation and are halogen-free.
