| MICROWAVE CORPORATION v03.0604 HMC345LP3 Features Broadband Performance: DC - 8.0 GHz High Isolation: 35 dB@ 6 GHz Low Insertion Loss: 2.2 dB@ 6 GHz Integrated Positive Supply 2:4 TTL Decoder 3 mm x 3 mm x 1 mm SMT Package GaAs MMIC SP4T NON-REFLECTIVE POSITIVE CONTROL 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 HMC345LP3 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. This switch also includes an on board binary decoder circuit which reduces the required logic control lines to two. The switch operates using a positive control voltage of 0/+5V, and requires a fixed bias of +5V. 14 SWITCHES - SMT * Blocking capacitors are required at ports RFC and RF1, 2, 3, & 4. Their value will determine the lowest transmission frequency.
