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. The SW-314 is ideally suited for
RF/IF communications applications. Environmental
screening is available. Contact the factory for
information.

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