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.

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.
