PRODUCT DESCRIPTION
The AWS5516 is a Single Pole Double Throw (SPDT)
GaAs MMIC switch assembled in a SOT-26 plastic
package. The AWS5516 is designed for applications
that require low insertion loss, high isolation, high
linearity, and small size. The switch can be controlled
with positive, negative, or a combination of both
voltages.

Notes:
1. DC blocking capacitors C1,2,3 and optional resistor Rs must be supplied externally.
2. C1,2,3 = 100 pF for operation >500MHz.
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.

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

The device may be operated safely over these conditions; however, parametric performance is guaranteed
only over the conditions defined in the electrical specifications.
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 ±
0.2V
