The datasheet is for HWS305, including product model, package type, pin layout, working temperature range, supplier, etc.
The document describes the HWS305, a general-purpose GaAs MMIC SPDT switch designed for analog and digital wireless communication systems. It features low insertion loss (0.35dB @ 2GHz) and very low DC power consumption in a low-cost SOT-26 plastic package.
The datasheet provides comprehensive electrical specifications including isolation, input power compression point (P1dB), third-order intermodulation intercept point (IP3), switching time, and control current. It also lists absolute maximum ratings for RF input power, control voltage, and operating temperature.
