CHT3091RCF Datasheet, PDF (1/3 Pages) United Monolithic Semiconductors – DC-40GHz Attenuator

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.

"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 and does NOT indicate the location of PIN
