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.
