Introduction

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.
