F1456 Description
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 bination of a digital step attenuator (DSA) and a KLINTM RF Digital Gain Amplifier.
