BGA7124
400 MHz to 2700 MHz 0.25 W high linearity silicon amplifier
Rev. 3 — 9 September 2010
Product data sheet
1. Product profile
1.1 General description
The BGA7124 MMIC is a one-stage amplifier, available in a low-cost leadless
surface-mount package. It delivers 25 dBm output power at 1 dB gain compression and
superior performance up to 2700 MHz. Its power saving features include easy quiescent
current adjustment enabling class-AB operation and logic-level shutdown control to
reduce the supply current to 4 μA.
1.2 Features and benefits
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 or 5 V single supply operation
All pins ESD protected
1.3 Applications
Wireless infrastructure (base station,
repeater, backhaul systems)
Broadband CPE/MoCA
E-metering
Satellite Master Antenna TV (SMATV)
WLAN/ISM/RFID
Industrial applications
