Description
The AS225-313LF is a 0.1 to 6 GHz PHEMT GaAs IC sinlge-pole,
double-throw (SPDT) antenna switch. Designed for WLAN
applications, this device is capable of switching 1 W microwave
signals with 3 V control voltage while maintaining high-linearity
performance. The switch covers the entire 802.11a, b, and g
frequency ranges. The low-loss, high-isolation, high-inearity and
low-cost features make this switch ideal for Wireless LAN
systems.
Figure 1 shows the functional block diagram of the AS225-313LF.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
