It requires external DC blocking capacitors on the RF ports, positive supply voltage and five individual bit control voltages. The MAATSS0022 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. 2 dB GND 1 dB VC4 GND 0.5 dB 10K VC5 0.1uF Vs RF2 Pin Configuration Pin No. Function Pin No. Function 1 VC1 6 RF Port 2 2 VC2 7 Ground 3 VC3 8 Ground 4 VC4 9 Ground 5 VC5 10 RF Port 1 The MAATSS0022 is fabricated using M/A-COM’s GaAs 1.0 micron process.

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 MAATSS0022 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 MAATSS0022 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. 4. 0 = 0.0 V ± 0.2 V, 1 = Vs = 5.0 V ± 0.2 V. 2 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.
