Overview
DATA SHEET SMV1771 Series: Hyperabrupt Junction Tuning Varactors Applications  Low-noise and wideband UHF and VHF VCOs  High-volume, low-cost battery-powered tuning circuits Features  Low series resistance  High capacitance ratio  SC-79 and ultra-small SOD-882 packages (MSL1, 260 °C per JEDEC J-STD-020) Skyworks GreenTM products are compliant with all applicable legislation and are halogen-free.
For additional information, refer to Skyworks Definition of GreenTM, document number SQ04–0074.
Description The SMV1771 series are silicon hyperabrupt junction varactor diodes specifically designed for battery operation.
The specified high capacitance ratio and low series resistance make these varactors appropriate for low phase noise Voltage-Controlled Oscillators (VCOs) used at frequencies in wireless systems up to and above 2.
5 GHz.
Table 1 describes the package and marking of the SMV1771 varactor series.
