1 / 28 page  T © 2016 Integrated Device Technology, Inc 1 October 19, 2016 TX Digital VGA 1400 MHz to 2300 MHz F1455 Datasheet Description The F1455 is a High Gain / High Linearity 1400 MHz to 2300 MHz TX Digital Variable Gain Amplifier used in transmitter applications. The F1455 TX DVGA provides 32.8 dB maximum gain with +38.5 dBm OIP3 and 3.9 dB noise figure. Up to 29.5 dB 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 5 V supply and 220 mA of ICC. This device is packaged in a 6 mm x 6 mm, 28-pin QFN with 50 Ω 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. The F1455 TX DVGA offers very high reliability due to its construction from a monolithic silicon die in a QFN package. The F1455 is configured to provide an optimum balance of noise and linearity performance consisting of a KLINTM RF amplifier, digital step attenuator (DSA) and a PA driver amplifier. The KLINTM amplifier maintains the OIP3 and output P1dB performance over an extended attenuation range when compared to competitive devices.
