Description
The SMV1269-074 is a dual silicon hyperabrupt junction
varactor diode in a common cathode configuration
specifically designed for battery operation.The specified
high capacitance ratio and low R
S
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.
