The MAAD-011048 from MACOM is a 5-Bit Digital Attenuator that operates from DC to 55 GHz. It has an attenuation range of 0 to 31 dB with a step size of 1 dB. It can handle an input power of up to 27 dBm and has an insertion loss of less than 4.7 dB. The attenuator has an integrated CMOS-compatible driver and is controlled with either an SPI-compatible serial interface or a 5-bit parallel word. It requires a DC supply of 3.3 V and is compatible with 1.8 V CMOS logic. The attenuator is available in a 20-pin surface-mount laminate package that measures 3.0 x 3.0 x 0.9 mm and is suitable for ISM and multi-market applications where high accuracy, low power consumption, and low intermodulation are required.
