IDTF0480NBGI Datasheet Matched Broadband RF VGA 400MHz to 2700MHz GENERAL DESCRIPTION FEATURES This document describes the specifications for the 400 MHz 2700 MHz IDTF0480 400 MHz to 2700 MHz RF Digital Variable Gain < 1 dB overshoot between gain transitions Amplifier used in receiver, transmitter and other 13 dB typical max gain applications. 23 dB gain range, 1 dB gain step resolution Excellent linearity +41 dBm OIP3 IDTF0480 RF DVGA provides 13 dB typical maximum Noise Figure 4 dB gain (no attenuation) with 4 dB noise figure and 23 dB I = 100 mA CC gain adjustment in 1 dB steps designed to operate 1.3 mA standby current with a single 5 V supply. Nominally, the device offers SPI interface +41 dBm output IP3 using 100 mA of I . CC 50 input and output impedance This device is packaged in a 5x5 32-pin thin QFN with Broadband, Internally Matched 50 ohm single-ended RF input and RF output Gain increases vs. frequency to counteract impedances for ease of integration into the signal-path system board losses lineup. 5x5 32-pin TQFN package DEVICE BLOCK DIAGRAM 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 TM combining a silicon Glitch-Free DSA & a Zero- TM Distortion RF amplifier in a single, compact QFN package. Utilizing IDTs 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.
