Features:

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.

Second, the characteristics
1. Low insertion loss (2 GHz): 1.0 dB

2, single positive power supply: VDD = +3V to +5V
