It is designed to offset the gain reduction of an RF component over temperature without the need for closed loop feedback. Three customer selectable temperature coefficients make it a flexible solution for RF lineups. It incorporates revolutionary new circuit architecture to solve a long standing industry problem with regards to attenuator architecture: high IP3, low DC current and broad bandwidth. Tradi- tional approaches for solving this problem require expensive co-fired ceramics with tempera- ture sensitive materials or current hungry PIN diodes with elaborate area consuming control circuits. This temperature compensating attenuator requires only a single supply voltage and two logic bits to set control attenuation slope versus temperature. The RFSA4013 draws a very low 1mA current and is packaged in a small 3mm x 3mm QFN. This attenuator is matched to 50 over its rated control range and frequency with no external matching components required.
