Overview
The HMC253AQS24TR, produced by Analog Devices Inc., is a low-cost, non-reflective Single-Pole, Eight-Throw (SP8T) switch. This GaAs MMIC (Monolithic Microwave Integrated Circuit) switch operates over a wide frequency range from DC to 2.5 GHz. It is packaged in a 24-lead QSOP (Quarter Size Outline Package) and features a single positive supply voltage of +5V. The switch includes an integrated 3:8 TTL decoder, which requires only three control lines and a positive bias to select each path, enhancing its functionality and reducing the complexity of the control circuitry.
