I. Overview
The HMC253AQS24E is a low cost, non-reflective SP6T switch in a 24-pin QSOP package with a wide operating frequency range from DC to 2.5 GHz. This switch provides single positive bias and true TTL/CMOS compatibility. The switch integrates a 3:6 decoder that requires only three control lines and one positive bias to select each path. The HMC253AQS24E SP8T replaces multiple configurations of SP4T and SPDT MMIC switches and logic drivers.
