| GaAs IC SPDT Low Loss Switch Reflective DC-4 GHz AS004L2-11 Features s Low DC Power Consumption s Low Loss, Reflective, Short s 8 Lead Hermetic Surface Mount Package s Capable of Meeting MIL-STD Requirements6 -11 ORIENTATION MARK 0.180 (4.57 mm) SQ. MAX. 0.150 (3.81 mm) 0.017 (0.43 mm) 0.013 (0.33 mm) 0.050 (1.27 mm) TYP. 0.400 (10.16 mm) 0.380 (9.65 mm) Description The AS004L2-11 SPDT low loss reflective switch operates from DC-4 GHz. The chip has a single series FET in each arm for low loss performance. This switch should be used when requirements call for low insertion loss and medium isolation. 0.006 (0.15 mm) 0.004 (0.10 mm) 0.070 (1.78 mm) 0.040 (1.02 mm) 0.075 (1.91 mm) MAX. 0.250 (6.35 mm) 0.200 (5.08 mm) Electrical Specifications at 25C Parameter1 Insertion Loss2 Frequency5 DC-1.0 GHz DC-2.0 GHz DC-4.0 GHz DC-1.0 GHz DC-2.0 GHz DC-4.0 GHz DC-1.0 GHz DC-4.0 GHz 40 34 26 Min.
