描述
The F2270 is a low insertion loss Voltage Variable RF Attenuator (VVA) covering a broad frequency range from 5MHz to 3000MHz. In addition to providing low insertion loss, the F2270 provides excellent linearity performance over its entire voltage control and attenuation range. The device uses a single positive supply voltage of 3.15V to 5.5V. 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 0V to 5V using either positive or negative control voltage slope.
