The SMV1247-040LF and SMV1249-040LF are silicon, surface mount hyperabrupt tuning varactor diodes designed for use as tuning elements in RF Voltage-Controlled Oscillators (VCOs), and voltage-tuned phase shifters and filters. The typical capacitance ratio from 0.3 V to 4.7 V is 10 for the SMV1247-040LF and 12 for the SMV1249-040LF, which makes these two varactors suitable for octive bandwidth VCOs, wide voltage range phase shifters, and wideband voltage-controlled filters. The SMV1247-040LF and SMV1249-040LF varactor diodes are provided in a surface mount package compatible with the industry-standard 0402 printed circuit board footprint.
