The MAAD-011045 from MACOM is a Digital Attenuator that operates from DC to 18 GHz. This 6-bit attenuator has an attenuation range from 0 to 31.5 dB with a step size of 0.5 dB. It can handle an input power up to 24 dBm and has an insertion loss of less than 5.25 dB. The attenuator has integrated CMOS/TTL compatible driver and maintains consistent phase across all attenuation states. It is controlled with either an SPI-compatible serial interface or a 6-bit parallel word. This attenuator requires a DC supply of 5 V and is compatible with 1.8 V, 2.5 V, 3.3 V, 5.0 V CMOS, and 5.0 V TTL Logic input. It is available in a 20-pin surface mount MMIC package that measures 0.11 x 0.354 x 0.11 inches.
