HMC344LP3

HMC344LP3 / 344LP3E v05.0505 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 8.0 GHz Typical Applications This switch is suitable for usage in DC - 8.0 GHz 50Ohm or 75-Ohm systems: • Broadband • Fiber Optics Features Broadband Performance: DC - 8.0 GHz High Isolation: 40 dB@ 6 GHz Low Insertion Loss: 1.8 dB@ 6 GHz Integrated 2:4 TTL Decoder LP3 SMT Package 8 SWITCHES - SMT • Switched Filter Banks • Wireless below 8 GHz Functional Diagram General Description The HMC344LP3 & HMC344LP3E are broadband non-reflective GaAs MESFET SP4T switches in 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.
