MAATSS0001-TB

Digital Attenuator, 5 Bit, 15.5 dB, 500 - 2500 MHz V 3.00 MAATSS0001 Features n 5 Bits, 0.5 dB Steps n Excellent Accuracy n Single Positive Control (+3 to +5V) n Small Low Cost QSOP-16 (SSOP-16) Package Functional Schematic VC5 VC4 VC3 VC2 VC1 0.5 dB 1 dB 8 dB 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 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 MAATSS0001 is fabricated using M/A-COM’s GaAs 1.0 micron process. The process features full chip passivation for increased performance and reliability.
