Description

M/A-COM's SW65-0440 is a GaAs MMIC absorptive
SP4T switch with an integral silicon ASIC driver. This
device is in a 24-lead plastic package. This switch offers
excellent broadband performance and repeatability from DC
to 3 GHz, while maintaining low DC power dissipation.
The SW65-0440 is ideally suited for wireless infrastructure
applications.

2. Operation of this device above any one of these
parameters may cause permanent damage.

3. When the RF input is applied to the terminated port, the
absolute maximum power is +30 dBm.

4. Standard CMOS TTL interface, latch-up will occur if logic
signal is applied prior to power supply.
