4230-52

Overview

The pSemi 4230-52 is a single-pole double-throw (SPDT) RF switch IC designed for general-purpose applications. It operates across a frequency range of DC to 3 GHz with a 50 Ohm impedance. The device features a minimum input third-order intercept point (IIP3) of 50 dBm and a typical insertion loss of 0.55 dB. It functions within a supply voltage range of 2.7 V to 3.3 V and supports an operating temperature range from -40°C to +85°C. The component is housed in an 8-MSOP package.
