Description

M/A-COM’s MAATSS0018 is a 1 bit, 10 dB step

GaAs MMIC digital attenuator in a lead-free SOT-25

surface mount plastic package. The MAATSS0018

is ideally suited for use where high accuracy, very

low power consumption and low intermodulation

products are required. Typical applications include

radio, wireless LANs, GPS equipment and other

gain/level control circuits.

The MAATSS0018 is a GaAs MMIC using a mature

1-micron process. The process features full chip

passivation for increased performance and reliability.

3. For positive voltage control, external DC blocking capacitors

are required on all RF ports (pins 1, 2 and 3)

4. Differential voltage, V(state 1) - V(state 0), must be +2.8 V

minimum and less than 8 V.

5. 0 = -8 V to 0.2 V, 1 = -0.2 V to 8 V

1. Exceeding any one or combination of these limits may cause

permanent damage to this device.

2. M/A-COM does not recommend sustained operation near

these survivability limits.
