Description
The SMV1265-040LF hyperabrupt junction tuning varactors is
designed for very high capacitance tuning ratios with low series
resistance, which makes this device especially attractive for
wideband voltage controlled oscillator (VCO) applications.
The packaging and marking information is shown in Table 1. The
absolute maximum ratings of the SMV1265-040LF are provided in
Table 2. Electrical specifications are specified in Table 3. Figure 1
shows the typical performance of capacitance versus voltage. The
SPICE model for the SMV1265-040LF is shown in Figure 2 and
the associated model parameters are provided in Table 4. The
relationship between voltage and capacitance for the
SMV1265-040LF is shown in Table 5.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. These
devices must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the
human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all
times.
