The HMC253AQS24E SP8T is a broadband RF switch in a 24-pin QSOP package that can replace SP4T and SPDT mmic switches and logic drivers in multiple configurations. Key benefits - Versatile replacement: consolidates SP4T and SPDT switching with a single part for multiple configurations, reducing BOM and design complexity. - Simple bias and compatibility: uses a single positive bias and offers true TTL/CMOS compatibility for easy integration. - Easy control with integrated decoder: a 3:6 decoder is integrated into the switch and requires only three control lines and a positive bias to select each path. - Cost-effective and reliable: non-reflective design delivers dependable performance across the operating range, delivering value without sacrificing quality. - Compact and broadband: compact 24-pin QSOP package with DC to 2.5 GHz broadband operation for flexible routing in tight layouts. Key attributes - Function: SP8T RF switch with eight selectable paths; supports multiple routing configurations. - Compatibility: TTL/CMOS compatible control signals; positive bias requirement simplifies interface. - Size and packaging: 24-pin QSOP enclosure for easy integration into compact assemblies. - Performance: broadband DC to 2.5 GHz; non-reflective design to minimize return loss and improve signal integrity. Typical applications - RF test benches and switch matrices where multiple signals must be routed without adding complex control logic. - Wireless and telecom front-ends requiring rapid, flexible path selection across wide bandwidths. - Instrumentation and lab automation where a single part can replace multiple switches and drivers to save space and cost.
