The MAAD-011048 from MACOM Technology Solutions Inc. is a wideband 5-bit, 1 dB step MMIC digital attenuator with a full 31 dB range. Operating over a frequency range of DC to 55 GHz, the device is compatible with 1,8 V CMOS logic. It is available in a lead-free 3 mm, 20-lead surface mount laminate package.
The attenuator is controlled with either a SPI-compatible serial interface or a 5-bit parallel word. SEROUT is same signal as the SERIN but delayed by six clock cycles, which is useful when using these attenuators in daisy-chain operation.
This device is ideally suited for use where high accuracy, very low power consumption, and low intermodulation products are required, such as the ISM market.
