BGA7127
400 MHz to 2700 MHz 0.5 W high linearity silicon amplifier
Rev. 01 — 26 July 2010
Product data sheet
1. Product profile
1.1 General description
The MMIC is a one-stage amplifier, offered in a low-cost leadless surface-mount
package. It delivers 28 dBm output power at 1 dB gain compression and a superior
performance up to 2700 MHz. Its power saving features include simple quiescent current
adjustment, which allows 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
12 dB small signal gain at 2 GHz
28 dBm output power at 1 dB gain compression
Integrated active biasing
External matching allows broad application optimization of the electrical performance
5 V single supply operation
All pins ESD protected
1.3 Applications
Broadband CPE/MoCA
WLAN/ISM/RFID
Wireless infrastructure (base station,
repeater, backhaul systems)
Industrial applications
E-metering
Satellite Master Antenna TV (SMATV)
