Device Overview
General Description
The MSW2-1001ELGA is a reflective, single-pole double throw (SPDT) switch. The part is manufactured using a Silicon-On-Insulator (SOI) process. The switch operates from 100MHz to 40GHz with average insertion loss and isolation of 1.2dB and 40dB respectively and input power handling and hot switching capability of 27 dBm. The MSW2-1001ELGA requires positive and negative 3.3V supply inputs and is controlled via a single input pin compatible with LVTTL logic. This switch has a 50-Ohm characteristic impedance. The MSW2-1001ELGA is packaged in a compact 2.25x2.25 mm LGA for surface mount integration on circuit board-based systems.
