THEORY OF OPERATION The AD831 consists of a mixer core, a limiting amplifier, a low noise output amplifier, and a bias circuit (Figure 1). The mixer’s RF input is converted into differential currents by a highly linear, Class A voltage-to-current ...
Page 8
AD831 The mixer has two open-collector outputs (differential currents) at pins IFN and IFP.These currents may be used to provide nominal unity gain by connecting a center-tapped transformer (1:1 turns ratio) to pins IFN and IFP as ...
Page 9
For gains other than unity, the amplifier’s output at OUT is connected via an attenuator network to VFB; this determines the overall gain. Using resistors R1 and R2 (Figure 6), the gain setting expression is Ê + ˆ ...

AD831 APPLICATIONS Careful component selection, circuit layout, power supply dc coupling, and shielding are needed to minimize the AD831’s susceptibility to interference from radio and TV stations, etc. In bench evaluation, we recommend placing all of the components in a ...

AD831 Connections Quadrature Demodulation Two AD831 mixers may have their RF inputs connected in parallel and have their LO inputs driven in phase quadrature (Figure 11) to provide demodulated in-phase (I) and quadrature (Q) outputs. �� ����� ����� Figure 11. ...
