| v04.0604 MICROWAVE CORPORATION HMC344LP3 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 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 8.0 GHz Typical Applications This switch is suitable for usage in DC - 8.0 GHz 50-Ohm or 75-Ohm systems: * Broadband * Fiber Optics * Switched Filter Banks * Wireless below 8 GHz Functional Diagram General Description The HMC344LP3 is a broadband non-reflective GaAs MESFET SP4T switch in a low cost leadless surface mount package. 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. 14 SWITCHES - SMT Electrical Specifications, TA = +25 C, With 0/-5V Control, 50 Ohm System Parameter Frequency DC - 2.0 GHz DC - 6.0 GHz DC - 8.0 GHz DC - 2.0 GHz DC - 4.0 GHz DC - 6.0 GHz DC - 8.0 GHz DC - 2.0 GHz DC - 4.0 GHz DC - 6.0 GHz DC - 8.0 GHz DC - 8.0 GHz 0.5 - 8.0 GHz 0.5 - 8.0 GHz DC - 8.0 GHz 35 150 ns ns 43 36 34 31 12 9 8 5 7 17 37 Min.
