HMC321LP4

HMC321LP4 / 321LP4E v03.0805 GaAs MMIC SP8T NON-REFLECTIVE POSITIVE CONTROL SWITCH, DC* - 8 GHz SWITCHES - SMT 10 10 - 172 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 Switched Filter Banks Wireless below 8 GHz OLETE Functional Diagram Integrated Positve Supply 3:8 TTL Decoder 4x4 mm SMT Package General Description The HMC321LP4 & HMC321LP4E are broadband nonreflective 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 positive 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. * 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. S Electrical Specifications, TA = +25° C, With 0/+5V Control, 50 Ohm System BParameter Frequency Min. Typ. Max.
