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.

Table 2: Absolute Minimum and Maximum Ratings
Table 3: Operating Ranges at 25 C
Notes:
1. All measurements made in a 50 Ohm system, unless other specified.
(2) Video feedthru measured with 1 ns rise time pulse and 500 MHz bandwidth.
(3) VCTL is the absolute value of the differential voltage from V1 to V2. Changing polarity selects the switch path as defined
in the truth table below. Use of the optional resistor Rs on the common port limits VHIGH to Vs 0.2 V.
ELECTRICAL CHARACTERISTICS
The device may be operated safely over these conditions; however, parametric performance is guaranteed only over
the conditions defined in the electrical specifications.
Stresses in excess of the absolute ratings may cause permanent damage.
Functional operation is not implied under these conditions. Exposure to
absolute ratings for extended periods of time may adversely affect reliability.
