Description
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.
