IDTF0480NBGI

Matched Broadband RF VGA GENERAL DESCRIPTION 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. 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 32-pin thin QFN with 50 ohm single-ended RF input and RF output impedances for ease of integration into the signal-path lineup. COMPETITIVE 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 Glitch-FreeTM DSA & a ZeroDistortionTM 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.
