HMC321LP4 / 321LP4E v03.0805 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 50- Broadband Performance: DC - 8 GHz Ohm or 75-Ohm systems: High Isolation: >30 dB 6 GHz Broadband Low Insertion Loss: 2.5 dB 6 GHz Fiber Optics Integrated Positve Supply 3:8 TTL Decoder Switched Filter Banks 4x4 mm SMT Package Wireless below 8 GHz Functional Diagram General Description The HMC321LP4 & HMC321LP4E are broadband non- re flective GaAs MESFET SP8T switches in low cost 10 leadless 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 fi xed bias of +5v. 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 Specifi cations, T = +25 C, With 0/+5V Control, 50 Ohm System A Parameter Frequency Min. Typ. Max.
