Description
M/A-COM’s SW-314 is a GaAs MMIC SP4T absorptive
switch with an integral silicon ASIC driver.
This
device is in a 24-lead ceramic surface mount package.
These switches exhibit excellent performance from DC to 3
GHz, with very low DC power dissipation.
SW-314 is ideally suited for RF/IF communications
applications. Environmental screening is available.

3. Operation of this device above any one of these parameters
may cause permanent damage.
4. When the input power is applied to the terminated port, the
absolute maximum is +30 dBm.
5. Standard CMOS TTL interface, latch-up will occur if logic
signal is applied prior to power supply.
