AN26218A
UMTS triple band LNA-IC
Overview
AN26218A is LNA-IC for 800 MHz / 1.7 GHz / 2.1 GHz Band Applications.
Realizing high performance by using 0.18
μm
SiGeC Bi-CMOS process(fT = 90 GHz, fmax = 140 GHz).
Each band is selectable and High/Low Gain-mode is changeable, controlled by integrated CMOS logic circuit.
Achieving miniaturization by using small size package.
