GaAs IC SPST Switch Reflective DC-18 GHz AS018R1-00 Features Chip Outline 1.388 Broadband DC-18 GHz Low Loss, High Isolation, Reflective, Short 1.270 100% On-Wafer RF and DC Testing 1.145 100% Visual Inspection to MIL-STD-883 MT 2010 0.727 Description 2.030 1.074 0.125 0.000 0.000 The AS018R1-00 GaAs SPST MMIC FET switch chip is ideal for applications requiring low loss, high isolation and/or broadband operation. The GaAs MMIC employs one series and three shunt FETs for low loss, high isolation switching. Each chip is measured on a 100% basis at 2, 10 and 18 GHz for insertion loss, isolation, input and output return losses and gate leakage. Power consumption is very low, typically 75 A at -5 V. While recommended for operation up to 18 GHz, the switch performs well through 26 GHz. Dimensions indicated in mm. All DC (V) pads are 0.1 x 0.1 mm and RF In, Out pads are 0.07 mm wide. Chip thickness = 0.1 mm. Electrical Specifications at 25C 2, 10 and 18 GHz 2 GHz Typ. 10 GHz Typ. 18 GHz Typ.
