RFMD + TriQuint = Qorvo RFSA4033 RFSA4033 Programmable Temperature Compensating Attenuator 5MHz to 6000MHz Package: QFN, 16-pin, 3.0mm x 3.0mm x 0.85mm The RFSA4033 is a fully monolithic linear-in-dB analog temperature compensating attenuator (TCA) featuring exceptional linearity over its entire Features gain control range. It is designed to offset the gain reduction of an RF Patented Circuit Architecture component over temperature without the need for closed loop feedback. Broadband 5MHz to 6000MHz Eight customer selectable scaled attenuation slopes and eight selectable Frequency Range nominal attenuation values at 25C creates a total combination of 64 64 Selectable Attenuation versus possible temperature coefficients which make it a flexible solution for RF Temperature Linear-in-dB Slopes lineups. It incorporates revolutionary new circuit architecture to solve a long +52dBm Input IP3 Typical standing industry problem with regards to attenuator architecture: high IP3, +80dBm Input IP2 Typical low DC current and broad bandwidth. Traditional approaches for solving this problem require expensive co-fired ceramics with temperature sensitive High 1dB Compression Point >+30dBm materials or current hungry PIN diodes with elaborate area consuming control circuits. This temperature compensating attenuator requires only a Low Residual Phase Noise <-140dBc/Hz at 10kHz offset 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 3V to 5V Power Supply matched to 50 over its rated control range and frequency with no external 3V Logic Compatible matching components required.
