The AMMP-6640 from Avago is a monolithic, voltage variable GaAs attenuator that operates from DC to 40 GHz. It provides an attenuation range of 20 dB with a 2 dB step size and an insertion loss of 5 dB. The attenuator can handle 30 dBm of input power and has a VSWR of 2.5:1. It is fabricated using an enhancement mode MMIC process and is available in a surface-mount package that measure 5 x 5 x 2 mm and is suitable for Microwave Radio Systems, Satellite Communication, and WiMAX applications.
