Brief Description
The CMX901 is a wideband RF power amplifier with high efficiency and high gain and may be used as a power amplifier or
driver amplifier. The device can be used for a wide range of frequencies from 130MHz to 950MHz. The power delivered
from the device depends on the power supply.
CMX901 can provide RF power as high as 2.5W with 4.0V supply. It is strongly recommended that the supply voltage
DOES NOT exceed 6V and the output power DOES NOT exceed 36dBm (4W).
