Description
Skyworks
silicon hyperabrupt junction varactor diodes are
processed using established
ion-implantation
technology
resulting in low series resistance, wide tuning ratio devices with
high Q values. These diodes are available as chips or in ceramic
packages. The planar chips have a small outline size (12 x 12
mils, nominal) and are fully passivated, which results
in low
leakage current and high reliability. These varactor chips are
intended for assembly in hybrid integrated circuit resonators used
in
Voltage Controlled Oscillators (VCOs) and analog tuned filters.
The absolute maximum ratings of the SMV2019-SMV2023
varactors are provided in Table 1. Electrical specifications are
specified in Table
2.
Typical capacitance values are listed in
Table 3.
The SPICE model is shown in Figure 1. SPICE parameters are
listed in Table 4. Typical performance characteristics are provided
in
Figures
2
and 3.

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.
CAUTION:
Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
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.
