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.
Technical Description
The SKY12146-321LF Variable Voltage Attenuator uses GaAs
pHEMTs as voltage-controlled attenuating elements. To maintain
impedance matching within operating frequencies, the GaAs
pHEMTs are coupled to the RF input and output through an
integrated hybrid-coupler. Since no temperature compensation is
used in this product, the attenuation value at any fixed bias
voltage varies with operating temperature.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY12146-321LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
Typical performance characteristics of the SKY12146-321LF are
illustrated in Figures 3 through 8.
