HMC245QS16

RF Switches Overview

The HMC245QS16 is a low-cost, non-reflective Single-Pole Triple-Throw (SP3T) switch implemented in Gallium Arsenide Monolithic Microwave Integrated Circuit (MMIC) technology. It operates from DC to 3.5 GHz and is housed in a 16-lead Quick Small Outline Package (QSOP). The device features a maximum operating temperature of +85°C and an operating supply voltage of 5V. Key electrical specifications include a P1dB compression point of 25 dBm and a characteristic impedance of 50 Ohms. This component is designed for general-purpose RF switching applications requiring minimal signal reflection.
