SMV1270-079
Description
The SMV1270-079 is a silicon hyperabrupt junction varactor
diode specifically designed for battery operation.The
specified high capacitance ratio and low RS of this varactor
make it appropriate for low noise VCOs used at frequencies
in wireless systems to beyond 2.5 GHz. Applications include
low noise and wideband UHF and VHF VCO for GSM, PCS,
CDMA and analog phones.
