F1456 TX Digital VGA 1500 MHz to 2950 MHz Datasheet The F1456 is a High Gain / High Linearity 1500MHz to 2950MHz TX Digital Variable Gain Amplifier used in transmitter applications. The F1456 TX DVGA provides 32.1dB maximum gain with +38dBm OIP3 and 3.9 dB noise figure. Up to 31.5dB 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 215mA of ICC. This device is packaged in a 6 mm x 6 mm, 28VFQFPN 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.
