General Description

The HMC344ALP3E is a broadband non-reflective GaAs MESFET SP4T switch in a low cost leadless surface mount packages. Covering DC to 8 GHz, this switch offers high isolation and low insertion loss and extends the frequency coverage of Hittite’s SP4T switch product line. This switch also includes an on board binary decoder circuit which reduces the required logic control lines to two. The switch operates using a negative control voltage of 0/-5V, and requires a fixed bias of -5V.
