DESCRIPTION
AN26025A is a single band LNA (Low Noise Amplifier)-
IC for 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).

Notes). This product may sustain permanent damage if subjected to conditions higher than the above stated absolute maximum rating.
This rating is the maximum rating and device operating at this range is not guaranteeable as it is higher than our stated
recommended operating range.
When subjected under the absolute maximum rating for a long time, the reliability of the product may be affected.
*1:The values under the condition not exceeding the above absolute maximum ratings and the power dissipation.
*2:Except for the operating ambient temperature, operating junction temperature and storage temperature,
all ratings are for Ta = 25°C.
*3:RF signal input pin. Do not apply DC. Do not apply more than 0 dBm to RF input.

Note). For the actual usage, please refer to the PD-Ta characteristics diagram in the package specification, supply
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
