HMC321ALP4E v03.0717 GaAs MMIC SP8T NON-REFLECTIVE POSITIVE CONTROL SWITCH, DC* - 8 GHz Typical Applications Features This switch is suitable for usage in DC - 8.0 GHz Broadband Performance: DC - 8 GHz 50-Ohm or 75-Ohm systems: High Isolation: >30 dB at 6 GHz Broadband Low Insertion Loss: 2.3 dB at 6 GHz Fiber Optics Integrated Positive Supply 3:8 TTL Decoder Switched Filter Banks 24 Lead 4x4mm QFN Package: 9 mm Wireless below 8 GHz Functional Diagram General Description The HMC321ALP4E is a broadband non- reflective GaAs SP8T switch in low cost lead - less surface mount packages. Covering DC to 8 GHz, this switch offers high isolation and low inser- tion loss. This switch also includes an on board binary decoder circuit which reduces the required logic con- trol lines to three. The switch operates using a positive control voltage of 0/+5 volts, and requires a fixed bias of +5 volts. This switch is suitable for usage in 50-Ohm or 75-Ohm systems. * DC blocking capacitors are required at ports RFC and RF1, 2, 3, 4, 5, 6, 7, 8. Their value will determine the lowest transmission frequency. Electrical Specifications, T = +25 C, With 0/+5V Control, 50 Ohm System A Parameter Frequency Min. Typ. Max.
