CHT4012-98F
Description
The CHT4012-98F is a DC-6GHz monolithic 6 bit digital attenuator with a LSB = 0.5d B offering a high dynamic range and a high accuracy, the RMS amplitude error is typically as low as 0.3d B. The circuit provides low insertion loss 2.5d B associated to input and output return losses better than 14d B. A CMOS and TTL patible 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 p HEMT process, 0.25µm gate length and electron beam gate lithography.
It is available in chip form
