Product Details

The HMC802ALP3E is a broadband bidirectional 1-bit GaAs IC digital attenuator in a low cost leadless sur - face mount package. This single positive control line digital attenuator utilizes off chip AC ground capac - itors for near DC operation, making it suitable for a wide variety of RF and IF applications. Covering DC to 10 GHz, the insertion loss is less than 3 dB typical and attenuation accuracy is excellent at ±0.6 dB typ - ical. The attenuator also features a high IIP3 of +55 dBm. One TTL/CMOS control input is used to select the attenuation state and a single Vdd bias of +5V is required.
