Overview
The HMC7992LP3DETR is a general-purpose, nonreflective, single-pole, four-throw (SP4T) switch designed by Analog Devices Inc. This silicon-based switch operates over a wide frequency range of 0.1 GHz to 6.0 GHz and is packaged in a leadless, surface-mount 16-Lead Lead Frame Chip Scale Package (LFCSP). It is ideal for various RF and microwave applications, particularly in cellular infrastructure, due to its high isolation and low insertion loss characteristics.
