Description
M/A-COM’s SW15-0314 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
SW15-0314 is ideally suited for wireless infrastructure
applications. Available with enhanced performance as fully
hermetic version. Environmentally screenable as SW-314.

1. All specifications apply when operated with bias voltages of +5V for Vcc and –5V for Vee.
2. When DC blocks are used, a 10K ohm return to GND is required on the RFC port.
