Datasheet

Voltage Variable RF Attenuator

1MHz to 3000MHz

FEATURES

GENERAL DESCRIPTION



Low Insertion Loss: 1.1dB @ 500MHz

Typical / Min IIP3: 60dBm / 46dBm

Typical / Min IIP2: 98dBm / 74dBm

33dB Attenuation Range

The IDTF2255 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 1MHz to 3000MHz. In

addition to providing low insertion loss, the IDTF2255

provides excellent linearity performance over its entire

voltage control and attenuation range.

Bi-directional RF ports

+36dBm Input P1dB compression

V_MODEpin allows either positive or negative

control response

The F2255 uses a single positive supply voltage of

3.15V to 5.25V. Other features include the V_MODEpin

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 3.6V

using either positive or negative control voltage slope.



Linear-in-dB attenuation characteristic

Supply voltage: 3.15V to 5.25V

V_CTRLrange: 0V to 3.6V using 5V supply

+105°C max operating temperature

3mm x 3mm, 16-pin QFN package
