Linear Slope VVA Defies Temperature Fluctuation

RFMD's RFSA2013 VVA offers linear slope vs. control voltage over broad temp rangeRFMW, Ltd. announces design and sales support for a temperature compensated voltage controlled attenuator. RFMD’s RFSA2013 provides a linear attenuation slope versus control voltage with very little sensitivity to temperature changes. PIN diode designs suffer from large attenuation shifts over temperature. The RFMD RFSA2013’s integrated temperature compensation overcomes this issue. Built on SOI technology, linearity exceeds that of FET based designs. IIP3 linearity of the RFSA2013 is >50dBm. SOI also provides superior, class 1C ESD protection. With insertion loss of 2.6dB and attenuation range of 30dB, this revolutionary attenuator serves 5V applications were temperature variations are a design concern. For 3.3V applications, the RFSA2023 provides the same outstanding performance.
