HMC347 v04.0907 GaAs MMIC SPDT NON-REFLECTIVE SWITCH, DC - 20 GHz Typical Applications Features This switch is suitable DC - 20 GHz applications: High Isolation: >40 dB 20 GHz Fiber Optics Low Insertion Loss: 1.6 dB 20 GHz Microwave Radio Non-Re ectivfl e Design Military Small Size: 1.3 x 0.8 x 0.1 mm Space 4 VSAT Functional Diagram General Description The HMC347 is a broadband non-re flective GaAs MESFET SPDT MMIC chip. Covering DC to 20 GHz, the switch offers high isolation and low insertion loss. The switch features over 50 dB isolation at lower frequencies and over 40 dB at higher frequencies due to the implementation of on-chip via hole structures. The switch operates using two negative control volt- age logic lines of -5/0V, requires no Vee and has no current consumption. The switch operates down to DC. The chip features coplanar I/Os that allow 100% RF testing prior to delivery to the customer. Electrical Specifi cations, T = +25 C, With 0/-5V Control, 50 Ohm System A Parameter Frequency Min. Typ.
