Introduction

The F2258 is a 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 50 MHz to 6000 MHz. In addition to providing low insertion loss, the F2258 provides excellent linearity performance over its entire voltage control and attenuation range. The F2258 uses a single positive supply voltage of 3.15 V to 5.25 V. Another feature includes multidirectional operation meaning the RF input can be applied to either RF1 or RF2 pins. Control voltage ranges from 0 V to 3.6 V.
