TX Digital VGA 450MHz to 1100MHz F1451 Datasheet Description The F1451 is a High Gain / High Linearity 450MHz to 1100MHz TX Digital Variable Gain Amplifier used in transmitter applications. The F1451 TX DVGA provides 32dB maximum gain with +41.5dBm OIP3 and 3.6dB noise figure. Up to 29.5dB gain control is achieved using the combination of a digital step attenuator (DSA) and a KLINTM RF Digital Gain Amplifier. This device uses a single 5V supply and 185mA of ICC. This device is packaged in a 6 × 6 mm, 28-pin VFQFPN with 50Ω single-ended RF input and RF output impedances for ease of integration into the signal-path. Competitive Advantage In typical Base Stations, RF VGAs are used in the TX traffic paths to drive the transmit power amplifier.
