Product Detail

6-Bit Digital Attenuator
The MAAD-000523 is a 6-bit, 0.5-dB step GaAs MMIC digital attenuator in a lead-free 4 mm 24 lead PQFN surface mount plastic package. This device is ideally suited for use where high accuracy, very low power consumption and low intermodulation products are required. Typical applications include Cellular Basestation RX/TX Line-up, Femtocells, and other gain / level control circuits. This attenuator is controlled with either a SPI compatible serial interface or a 6 bit parallel word.
