Overview
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.
The F1451 TX DVGA offers very high reliability due to its construction from a monolithic silicon die in a QFN package.
The F1451 is configured to provide an optimum balance of noise and linearity performance consisting of a KLINTM RF amplifier, dig...
