CHT3091RCF

CHT3091RCF DC-40GHz Attenuator GaAs Monolithic Microwave IC in SMD leadless package Description The monolithic microwave IC (MMIC) in the package is a variable DC-40GHz attenuator. It is designed for a wide range of applications, from military to commercial communication systems. The circuit is manufactured with a MESFET process, 0.7µm gate length, via holes through the substrate and air bridges. It is supplied in a new SMD leadless chip carrier. Main Features ■ Broad band performance: DC-40GHz ■ Minimum attenuation [S21] : 4dB ( VS = 0V; VP = -5V ) ■ Maximum attenuation [S21] : 20dB ( VS = -5V; VP = 0V ) ■ Minimum input 1dB compression point (P-1dB) : 14dBm ■ SMD leadless package ■ Dimensions: 5.08 x 5.08 x 0.97 mm3 SMD Package Dimensions not to scale; not all details shown; dimensions are in millimeters [inches] 1.02 [0.04] 2.46 [0.10] 5.08 [0.20] 0.46 [0.02] 5 6 7 EXPOSED GROUND PAD CONNECT TO RF GROUND PLANE UMS CHT3091 PIN 1 Index 5.08 [0.20] PIN Function 1 2 3 4 Vs NC Vp RF out 4 8 2.46 [0.10] 3 0.97 [0.038] PIN 5 6 7 8 Function NC NC NC RF in 2 0.91 [0.036] 1 "Please note that PIN 1 is located in the lower left corner of the package (front-side view) for all SMD-type packages from United Monolithic Semiconductors. It is indicated by a triangle on the package lid. Starting with PIN 1 the other pads are numbered counter-clockwise (front-side view). ATTENTION: The dot on the backside of the package (i.e. side with metallic pads) is just for fabrication purposes ...
