75Ω Voltage Variable Attenuator

5MHz to 3000MHz

F2270

Datasheet

January 16, 2019

Description

The F2270 is a 75Ω, low insertion loss voltage variable RF

attenuator (VVA) designed for a multitude of wireless and other RF

applications. This device covers a broad frequency range from

5MHz to 3000MHz. In addition to providing low insertion loss, the

F2270 provides excellent linearity performance over its entire

attenuation range.

The F2270 uses a positive supply voltage of 3.3V or 5V. Other

features include a VMODE pin allowing either a positive or negative

voltage control slope versus attenuation and multi-directional

operation where the RF input can be applied to either the RF1 or

RF2 pins. The attenuation control voltage range is from 0V to 5V

using either a 3.3V or 5V power supply.

Competitive Advantage

The F2270 provides extremely low insertion loss and superb IP3,

IP2, return loss performance, and slope linearity across the control

range. Compared to the previous state-of-the-art for silicon VVAs,

this device provides superior performance:



Operation down to 5MHz



Insertion loss at 300MHz of 1.1dB



Typical attenuation slope: 10dB/Volt



Minimum OIP3 (maximum attenuation): +35dBm



Minimum IIP2 (maximum attenuation, > 35MHz): +85dBm

Typical Applications



CATV/Broadband Applications



Headend



Fiber/HFC Distribution Nodes



CATV Test Equipment
