Overview
The HMC1118LP3DETR, produced by Analog Devices Inc., is a general-purpose, broadband, nonreflective single-pole, double-throw (SPDT) switch. It is packaged in a 3 mm × 3 mm, surface mount LFCSP package. This switch is designed to operate over a wide frequency range of 9 kHz to 13.0 GHz, offering high isolation and low insertion loss. It is controlled using positive control voltage logic lines of +3.3 V and 0 V and requires +3.3 V and −2.5 V supplies. The HMC1118 is internally matched to 50 Ω at the RF input and output ports, eliminating the need for external matching components.
