This document describes the specifications for the

IDTF0480 400 MHz to 2700 MHz RF Digital Variable Gain

Amplifier used in receiver, transmitter and other

applications.

•

400 MHz – 2700 MHz

< 1 dB overshoot between gain transitions

13 dB typical max gain

23 dB gain range, 1 dB gain step resolution

Excellent linearity +41 dBm OIP3

Noise Figure 4 dB

IDTF0480 RF DVGA provides 13 dB typical maximum

gain (no attenuation) with 4 dB noise figure and 23 dB

gain adjustment in 1 dB steps designed to operate

with a single 5 V supply. Nominally, the device offers

+41 dBm output IP3 using 100 mA of I_CC.

_CC= 100 mA

1.3 mA standby current

50 ꢁ input and output impedance

Broadband, Internally Matched

Gain increases vs. frequency to counteract

system board losses

This device is packaged in a 5x5 32ꢀpin thin QFN with

50 ohm singleꢀended RF input and RF output

impedances for ease of integration into the signalꢀpath

lineup.

ADVANTAGE

In many applications, digital step attenuators followed

by RF amplifiers are used in the Receive path. The

IDTF0480 RF DVGA provides very high reliability by

combining a silicon GlitchꢀFree^TMDSA & a Zeroꢀ

Distortion^TMRF amplifier in a single, compact QFN

package. Utilizing IDT’s technology, the resultant RF

VGA provides +41 dBm OIP3 performance across a very

wide bandwidth of 400 MHz to 2700 MHz at

approximately 100 mA of current. Furthermore the

device is internally matched so there is no need to

optimize external matching elements.
