M/A-COM announces an RoHS-compliant 5-bit serial controlled attenuator for applications that require accuracy and monotonic performance. M/A-COM’s MAATSS0022 is a 0.5 dB step GaAs MMIC digital attenuator with 15.5 dB attenuation range in a lead-free MSOP-10 package. The digital attenuator requires external DC blocking capacitors on the RF ports, single positive supply voltage and five individual bit control voltages. The MAATSS0022 is suited for products that require high attenuation accuracy, low insertion loss and low intermodulation. Typical applications include basestations, wireless data, and wireless local loop gain level control circuits.
