Features Integrated CMOS/TTL Compatible Driver Parallel & Serial (P/S) Control with power-up state selection Insertion Loss: 1.6 dB typical @ 2.1 GHz IP3: 50 dBm typical @ 2 GHz Attenuation Accuracy: +/-(0.4 + 4% of attenuation setting) dB 0.5-dB Attenuation Steps to 31.5 dB Useable from 0.4 to 8.0 GHz Lead-Free 4 mm 24-Lead PQFN Package Halogen-Free “Green” Mold Compound RoHS* Compliant and 260°C Re-flow Compatible Small Relative Phase Variation per Bit 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. Functional Schematic 3,4 3. Blocking capacitors are required on all RF ports. 4. For optimum RF performance all N/C’s should be terminated to GND.
