T TX Digital VGA 2100 MHz to 2950 MHz F1456 Datasheet Description The F1456 is a High Gain / High Linearity 2100 MHz to 2950 MHz TX Digital Variable Gain Amplifier used in transmitter applications. The F1456 TX DVGA provides 32.1 dB maximum gain with +38 dBm OIP3 and 3.9 dB noise figure. Up to 31.5 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 215 mA of ICC. This device is pa.

T TX Digital VGA 2100 MHz to 2950 MHz F1456 Datasheet Description The F1456 is a High Gain / High Linearity 2100 MHz to 2950 MHz TX Digital Variable Gain Amplifier used in transmitter applications. The F1456 TX DVGA provides 32.1 dB maximum gain with +38 dBm OIP3 and 3.9 dB noise figure. Up to 31.5 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 215 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 F1456 TX DVGA offers very high reliability due to its construction from a monolithic silicon die in a QFN package. The F1456 is configured to provide an optimum balance of noise and linearity performance consisting of a KLINTM R.
