The HMC241LP3 & HMC241LP3E are general purpose non-reflective SP4T switches in low cost leadless surface mount packages. Covering DC - 4.0 GHz, this switch offers high isolation and has a low insertion loss of 0.7 dB at 2 GHz. The switch offers a single positive bias and true TTL/CMOS compatibility. A 2:4 decoder is integrated on the switch requiring only 2 control lines and a positive bias to select each path, replacing 4 to 8 control lines normally required by GaAs SP4T switches.
