The RFSA4033 is a fully monolithic linear-in-dB 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.
Eight customer selectable scaled attenuation slopes and eight selectable
nominal attenuation values at 25°C creates a total combination of 64
possible temperature coefficients which 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 6 logic bits to set the temperature coefficient. The
RFSA4033 is packaged in a small 3mm x 3mm QFN. This attenuator is
matched to 50Ω over its rated control range and frequency with no external
matching components required.
