Description

The SMV1270 series are silicon hyperabrupt junction varactor

diodes specifically designed for battery operation. The specified

high capacitance ratio and low reverse voltage make these

varactors appropriate for low-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 SMV1270

series varactors.
