RFMW, Ltd. announces design and sales support for ParkerVision’s direct conversion quadrature demodulator / modulator designed for communication systems requiring excellent linearity with the lowest possible power consumption. Drawing only 23mA from a 3V supply, the PV5870 consumes 1/5th to 1/10th the power of similar demodulators yet provides superior noise figure performance (a 6dB improvement over the nearest competitor). As a demodulator operating from 400 – 3600MHz, the PV5870 offers excellent amplitude and phase balance and very low DC offset. Intermodulation products IM2 and IM3 can be optimized through adjustment. RF, LO and baseband interfaces are fully differential. The baseband…
