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 ICC.

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 GlitchꢀFreeTM DSA & a Zeroꢀ  
DistortionTM RF 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.
