Overview
T TX Digital VGA 700 MHz to 1100 MHz F1451 Datasheet Description The F1451 is a High Gain / High Linearity 700 MHz to 1100 MHz TX Digital Variable Gain Amplifier used in transmitter applications.
The F1451 TX DVGA provides 32 dB maximum gain with +41.
5 dBm OIP3 and 3.
6 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 185 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 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 ...
