GENERAL DESCRIPTION
The F1423 is a 600 MHz to 3000 MHz TX differential
input / single-ended output RF amplifier used in
transmitter applications.
The F1423 TX Amp provides 13.1 dB gain with
+41.8 dBm OIP3 and 5.1 dB noise figure at 2000 MHz.
This device uses a single 5 V supply and 120 mA of ICC.
This device is packaged in a 4mm x 4mm, 24-pin Thin
QFN with 50 ohm differential RF input and 50 ohm
single ended RF output impedances for ease of
integration into the signal-path.
COMPETITIVE ADVANTAGE
In typical Base Stations, RF Amplifiers are used in the
TX traffic paths to drive the transmit power amplifier.
The F1423 TX Amplifier offers very high reliability due
to its construction using silicon die in a QFN package.
The F1423 includes a broadband differential input to
accept AC-coupled signals directly from a balanced
modulator or RF DAC architecture.
APPLICATIONS
• Multi-mode, Multi-carrier Transmitters
• GSM850/900 Base Stations
• PCS1900 Base Stations
• DCS1800 Base Stations
• WiMAX and LTE Base Stations
• UMTS/WCDMA 3G Base Stations
• PHS/PAS Base Stations
• Public Safety Infrastructure
