Description
The SMV123x series of silicon hyperabrupt junction varactor
diodes are designed for use in Voltage Controlled Oscillators
(VCOs) with a low tuning voltage operation. The low resistance of
these varactors makes them appropriate for high-Q resonators in
wireless system VCOs to frequencies over 10
GHz.
This family of
varactors is characterized for capacitance and resistance over
temperature.
Table 1 describes the various packages and markings of the
SMV123x varactors.

Package and Handling Information
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The SMV123x series of varactors are rated to Moisture Sensitivity
Level 1 (MSL1) at 260
°C.
They can be used for lead or lead-free
soldering. For additional information, refer to the Skyworks
Application Note,
Solder Reflow Information,
document number
200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.

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. 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. The
SMV123x varactors are Class 1B Human Body Model (HBM) ESD devices.
