HMC322LP4 / 322LP4E v05.1205 GaAs MMIC SP8T NON-REFLECTIVE SWITCH, DC - 8 GHz Typical Applications Features This switch is suitable for usage in DC - 8.0 GHz 50Ohm or 75-Ohm systems: Broadband Performance: DC - 8.0 GHz High Isolation: >30 dB@ 6 GHz • Broadband Low Insertion Loss: 2.4 dB@ 6 GHz • Fiber Optics Integrated 3:8 TTL Decoder • Switched Filter Banks 4x4 mm SMT Package • Wireless below 8 GHz General Description Functional Diagram The HMC322LP4 & HMC322LP4E are broadband non-reflective GaAs MESFET SP8T switches in low cost leadless surface mount packages. 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 three. The switch operates using a negative control voltage of 0/-5 volts, and requires a fixed bias of -5V. This switch is suitable for usage in 50-Ohm or 75-Ohm systems.
