GaAs Monolithic Microwave IC
Description
The CHT4012a98F 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 14dB. A CMOS and TTL compatible interface is available on chip. The circuit is mainly dedicated to defence and space systems and is also well suited for a wide range of microwave applications and systems.
The circuit is manufactured with a pHEMT process, 0.25µm gate length and electron beam gate lithography.
It is available in chip form
