PRODUCT DESCRIPTION
The AWS5502 is a Single Pole Double Throw GaAs
MMIC Switch assembled in a SOT-6 plastic package.
The AWS5502 is designed for analog and digital
application that require low insertion loss,
small size,
and low cost. State selection is achieved with
a complimentary positive voltage (requires positive
bias Vs, and blocking caps) or negative voltage
(no Vs or blocking caps required).

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.

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 otherwise specified.
2. DC = 300 kHz.
3. Insertion loss changes by 0.003 dB/°C.
4. Insertion loss state.
5. Video feedthru measured wirh 1 ns rise time pulse and 500 MHz bandwidth.
