The HMC241ALP3ETR is a general purpose non-reflective GaAs MMIC SP4T Switch covering DC to 4GHz, this switch offers high isolation and has a low insertion loss of 0.7dB at 2GHz. 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.
