The QPC1008 from Qorvo is a GaAs MMIC 5-Bit Digital Step Attenuator combined with a 1 dB voltage variable attenuator (VVA). It has a frequency range from DC to 20 GHz with an attenuation range of 31 dB with a step size of 1 dB. Each digital bit is controlled by a single voltage of either 0 V or -5 V, while the VVA is controlled using a single voltage varied from -5 V to 0 V. This step attenuator achieves a total attenuation of 32 dB when the digital bits and VVA is combined. It is available in a surface-mount leadless package that measures 3.9 x 3.9 mm and is suitable for use in electronic warfare, test and measurement, radar, and phased array applications.
