HMC345ALP3E v01.0818 GaAs MMIC SP4T 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: 35 dB 6 GHz Broadband Low Insertion Loss: 2.0 dB 6 GHz Fiber Optics Integrated Positive Supply 2:4 TTL Decoder Switched Filter Banks 16 Lead 3x3mm QFN Package: 9 mm Wireless below 8 GHz Functional Diagram General Description The HMC345ALP3E is a broadband non-reflective GaAs MESFET SP4T switch in a 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 two. The switch operates using a positive control voltage of 0/+5V, and requires a fixed bias of +5V. * Blocking capacitors are required at ports RFC and RF1, 2, 3, & 4. 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.
