AMMC-6650 DC–40 GHz Variable Attenuator
Data Sheet
Chip Size: 1530 μm x 660 µm (61.2 x 26.4 mils) Chip Size Tolerance: ±10 µm (±0.4 mils) Chip Thickness: 100 ± 10 µm (4 ±0.4 mils) Pad Dimensions: 80 x 120 µm (3.2 x 4.8 mils)
Description
The AMMC-6650 is a voltage controlled variable attenuator designed to operate from DC-40 GHz. It is fabricated using Avago Technologies enhancement mode pHEMT MMIC process with backside ground vias, and gate lengths of approximately 0.25um. The distributed topology of the AMMC-6650 facilitates broadband operation by absorbing parasitic effects of its series and shunt FETs. An on-chip DC reference circuit may be used to maintain optimum VSWR for any attenuation setting or to provide more linear attenuation versus voltage response.
