RoHS Compliant Digital Attenuator, 5-Bit, 15.5 dB 400 - 2500 MHz Features * * * * * * * * 5 Bits, 0.5 dB Steps Excellent Accuracy Single Positive Control (+3 V to +5 V) Lead-Free QSOP-16 (SSOP-16) Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Reflow Compatible RoHS* Compliant Version of MAATSS0001 MAATSS0017 V2 Functional Schematic Description M/A-COM's MAATSS0017 is a 0.5 dB step GaAs MMIC digital attenuator with 15.5 dB attenuation range in a lead-free QSOP-16 (SSOP-16) package. It requires external DC blocking capacitors on the RF ports, positive supply voltage and five individual bit control voltages. The MAATSS0017 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include base stations, wireless data, and wireless local loop gain level control circuits. The MAATSS0017 is fabricated using M/A-COM's GaAs 1.0 micron process. The process features full chip passivation for increased performance and reliability.

The difference between +3 V and +5 V operation is minimal for small signal performance. IIP3, however, is a strong function of voltage. +3 V is the minimum voltage at which the product will reliably operate. The MAATSS0017 requires a parallel interface that allows the user to enter a 5 bit digital word. Each state increments the attenuation by 0.5 dB giving a total range of 15.5 dB. The MAATSS0017 is not internally DC blocked. This means that the device requires DC blocking capacitors on the RF1 and RF2 ports. M/A-COM recommends 0.1 uF to allow for the entire frequency range to be utilized. Higher frequency applications can use smaller value capacitors as DC blocks.
