The F2255 is a low insertion loss Voltage Variable RF Attenuator (VVA) that covers a broad frequency 范围 from 1MHz to 3000MHz. In addition to providing low insertion loss, the F2255 provides 高 linearity and low return loss performance over entire frequency, voltage control and attenuation 范围s. The device uses a single positive supply voltage of 3.15V to 5.25V. 其他 特征 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. This device has a wide control voltage 范围 using either a positive or negative control voltage slope.
