AMMC-6630
5 – 45 GHz Variable Attenuator
Data Sheet
Description
The AMMC-6630 MMIC is a monolithic, voltage variable,
GaAs IC attenuator that operates from 5-45 GHz. It is fab-
ricated using Avago Technologies enhancement mode
MMIC process with backside ground vias, and gate
lengths of approximately 0.25um. The attenuator has
a distributed topology and it helps to absorb parasitic
effects of its series and shunt FETs to make it broadband.

Notes:
1. Attenuation is a positive number; whereas, S21 as measured on a Network Analyzer is a negative number.
2. Data obtained from on-wafer measurements.
3. Distribution data based on 5000 part sample size from two wafer lots during initial characterization of this product. Future wafers allocated to
this product may have nominal values anywhere between upper and lower limits.
