Wideband Voltage Variable RF Attenuator

The F2250 is a low insertion loss Voltage Variable RF Attenuator (VVA) covers a broad frequency range from 50 MHz to 6000 MHz.  In addition to providing low insertion loss, the F2250 provides excellent linearity performance over its entire voltage control and attenuation range. The device uses a single positive supply voltage of 3.15 V to 5.25 V.  Other features include the VMODE pin allowing either positive or negative voltage control slope vs attenuation and multi-directional operation meaning the RF input can be applied to either RF1 or RF2 pins.  Control voltage ranges from 0 V to 2.8 V using either positive or negative control voltage slope.
