The CHT4012-QDG is a DC-6GHz monolithic 6-bit digital attenuator with a LSB = 0.5dB offering a high dynamic range and a high accuracy, the RMS amplitude error is typically as low as 0.3dB. The circuit provides low insertion loss 2.5dB associated to input and output return losses better than 13dB. A CMOS and TTL compatible interface is available on chip. It is designed for a wide range of applications, from military to commercial communication systems. The circuit is manufactured with a pHEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is supplied in RoHS compliant SMD package.
