SKYWORKS AS179-92LF RF Switch IC, SPDT, 20MHz to 3GHz, SC-70-6

The SKYWORKS AS179-92LF is a high-performance, Single Pole Double Throw (SPDT) RF switch designed using advanced pHEMT GaAs FET technology. It operates across a broad frequency range from 20MHz to an impressive 3GHz, making it an exceptionally versatile component for modern RF and communication systems.

A key feature of this device is its low insertion loss, specified at a typical 0.3dB at 0.9GHz, which ensures minimal signal degradation in the transmission path. It is engineered for positive voltage operation with a very low DC power consumption, enhancing energy efficiency in portable and battery-powered applications. The switch delivers robust performance with a +30dBm typical Input 1dB Compression Point (IP1dB) and a high +43dBm typical Third-Order Intercept Point (IIP3) at 3V, providing excellent linearity and handling capability for strong signals.

Applications

This RF switch is ideally suited for a wide array of applications within communications and networking infrastructure. Its reliable performance and compact form factor make it a preferred choice for designers.
