Digital Attenuator, 5 Bit, 15.5 dB,

500 - 2500 MHz

Features

Description

The M/A-COM MAATSS0001 is a 0.5 dB step GaAs

MMIC digital attenuator with 15.5 dB dynamic range in a

low cost QSOP-16 (SSOP-16) package. It requires external

DC blocking capacitors on the RF ports, positive supply

voltage and five individual bit control voltages. It is par-

ticularly suited where high attenuation accuracy, low inser-

tion loss and low intermodulation products are required.

Typical applications include base stations, wireless data,

and wireless local loop gain level control circuits.

The MAATSS0001 is fabricated using M/A-COM’s GaAs

1.0 micron process.

passivation for increased performance and reliability.
