Description
The AS225-313LF is a 0.1 to 6 GHz PHEMT GaAs IC single-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.
The pin configuration and package are shown in Figure 2. Signal
pin assignments and functional pin descriptions are provided in
Table 1.
