Qorvo's RFSA4023 is a fully monolithic analog temperature compensating attenuator (TCA) featuring exceptional linearity over its entire gain control range. 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. Traditional approaches for solving this problem require expensive co-fired ceramics with temperature 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 RFSA4023 draws a very low 1mA current and is packaged in a small 3mm x 3mm QFN. This attenuator is matched to 50 ohm over its rated control range and frequency with no external matching components required.\n
