SMV114x Series: Hyperabrupt Junction Tuning Varactors

Applications

• High volume commercial systems

Features

• Frequency linear design

• Low series resistance

• Packages rated MSL1, 260 °C per JEDEC J-STD-020

Description

The SMV114x series of silicon hyperabrupt junction varactor

diodes is specifically designed with an increasing gamma versus

voltage characteristic. This results in improved Voltage-Controlled

Oscillator (VCO) frequency-voltage linearity compared to a

conventional hyperabrupt junction varactor.

The SMV114x family of varactors is characterized for capacitance

and resistance over temperature.

Table 1 describes the various packages and markings of the

SMV114x varactors.

Note: 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

SMV114x varactors are Class 0 Human Body Model (HBM) ESD devices.

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 SMV114x 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.
