PRODUCT DESCRIPTION
The AWS5518 is a Single Pole Double Throw (SPDT)
GaAs MMIC switch assembled in a SOT-26 plastic
package. The AWS5518 is designed for applications
APPLICATIONS
Transmit/Receive Switch
Diversity Switching
Antenna Selection
Notes:
1. DC blocking capacitors C1,2,3 and optional resistor Rs
must be supplied externally.
2. C1,2,3 = 100 pF for operation >500 MHz.
3. The use of resistor Rs to the positive voltage supply is
optional. It is only required if it is necessary to independently
control the RF ports, such as selecting both ports to be OFF
at the same time.
