Applications | 2 AD831 provides 24 dBm third order point which can achieve 10 dBm LO power consumption It does not require high power LO drivers and there is no corresponding shielding and isolation problems Therefore compared with passive mixers it can improve System performance reduce system cost |
---|---|
4 A single resistor connected between pins OUT and FB is used to set the gain The amplifier has low DC offset characteristics so it can be used for DC coupling applications such as DC baseband frequency conversion and quadrature amplitude | |
Demodulation | 3 The mixer is designed to be powered by a single power supply and the RF IF and LO ports have DC isolation capacitors for easy use The operating frequency of the RF and LO inputs can be as high as 500MHz The IF output is a single ended voltage output It has an output bandwidth of 250 |
MHz | 5 With the output amplifier of the mixer and the best source impedance the SSB noise figure of the mixer is 10 3 dB at 70 MHz Unlike passive mixers AD831 has no insertion loss no external duplexer and no passive termination AD8362 has two working |
Modes | Power measurement and controller In Figure 1 in the power measurement mode VOUT and VSET |
