SMV1705 Series: Hyperabrupt Junction Tuning Varactors

Applications

 Low-noise and wideband UHF and VHF VCOs

 High volume, low-cost batteries

Features

 Low series resistance

 High capacitance ratio

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

Skyworks Green™ products are compliant with

all applicable legislation and are halogen-free.

For additional information, refer to Skyworks

Deﬁnition of Green™, document number

SQ04-0074.

Description

The SMV1705 group of silicon hyperabrupt junction varactor

diodes is specifically designed for battery operation. The specified

high capacitance ratio and low reverse voltage of these varactors

make them appropriate for low-noise voltage controlled

oscillators (VCOs) used at frequencies in wireless systems up to

and above 10 GHz.

Table 1 describes the various packages and markings of the

SMV1705 group of varactors.

Electrical and Mechanical Specifications

The absolute maximum ratings of the SMV1705 group of

varactors are provided in Table 2. Electrical specifications are

provided in Table 3. Typical capacitance values are listed in

Table 4. Typical performance characteristics of the SMV1705

varactors are illustrated in Figures 1 and 2.

The SPICE model for the SMV1705 varactors is shown in Figure 3

and the associated model parameters are provided in Table 5.

Package Dimensions

Package dimensions are shown in Figures 4 to 8 (even numbers),

and tape and reel dimensions are provided in Figures 5 to 9 (odd

numbers).

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 SMV1705 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.

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.

ESD HANDLING: 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 when handling or transporting. Static charges may easily produce

potentials of several kilovolts on the human body or equipment, which can discharge without detection.

Industry-standard ESD handling precautions should be used at all times.
