Objective data sheet
1. Product profile
1.1 General description
The BGA7124 MMIC is a one-stage driver amplifier, offered in a low-cost leadless
surface-mount package. It delivers 25 dBm output power at 1 dB gain compression and a
superior performance for various narrowband-tuned application circuits for frequencies up
to 2700 MHz.
1.2 Features
400 MHz to 2700 MHz frequency operating range
16 dB small signal gain at 2 GHz
25 dBm output power at 1 dB gain compression
Integrated active biasing
External matching allows broad application optimization of the electrical performance
3.3 V / 5 V single supply operation
Power savings features:
Simple quiescent current adjustment allows class-AB operation
Logic-level shutdown control pin reduces supply current to 4 μA
ESD protection at all pins
1.3 Applications
Wireless infrastructure (base station, repeater)
E-metering
Broadband CPE
Satellite Master Antenna TV (SMATV)
Industrial applications
W-LAN / ISM / RFID
