General Description

The ATN10-00110 is a family of precision GaAs MMIC fixed attenuators. These attenuators are an ideal solution for attenuating a signal and they can be used in a wide range of applications. They are ideal for test equipment’s protection and signal overload prevention in various RF circuitry. A 50-ohm match is maintained over the entire operating frequency range.

Specifications

Absolute Maximum Ratings

The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If these limits are exceeded, the device may be inoperable or have a reduced lifetime.

ParameterMaximum RatingUnit
DC Current, any pin 100mA
Maximum Operating Temperature 100°C
Maximum Storage Temperature 125°C
Minimum Operating Temperature -55°C
Minimum Storage Temperature -65°C
RF Power Handling 12W

Reliability ratings are individual, a combination of stresses (DC current, RF power, and heat) may cause premature failure).

[1] Actual failure observed at 4W at 2 GHz with a baseplate temperature of 23°C. Power handling will derate with frequency and temperature.
