GENERAL DESCRIPTION

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.
