SMV1763-079

Description

The SMV1763-079 is a silicon hyperabrupt junction varactor

diode specifically designed for 3 V platforms.The specified

high capacitance ratio and low RS of this varactor make it

attractive for low phase noise VCOs in wireless systems up

to and beyond 2.5 GHz. Applications include low noise and

wideband UHF and VHF VCO for GSM, PCS, CDMA and

analog phones.
