DESCRIPTION
AN26031A is a single band LNA (Low Noise Amplifier)-
IC for 2.5 GHz Band applications.
Realizing high performance by using 0.18 µm SiGeC
Bi-CMOS process (f
T
= 90 GHz, f
max
= 140 GHz).
High/Low Gain-mode is changeable, controlled by
integrated CMOS logic circuit.
Achieving miniaturization by using small size Wafer
Level Chip Size Package (WLCSP).
+2.5 dBm typ. (High-Gain mode)

voltage, load and ambient temperature conditions to ensure that there is enough margin follow the power and
the thermal design does not exceed the allowable value.
CAUTION
Although this has limited built-in ESD protection circuit, but permanent damage may occur on it.
Therefore, proper ESD precautions are recommended to avoid electrostatic damage to the MOS gates
