functional description 3 - 4 tda 6131 preliminary wireless components specification, march 2000 3.4 circuit description 3.4.1 mixer the mixer used in this design is a general purpose up-/down conversion gilbert cell mixer that can be used in various configurations.the rf can enter the ic either via the pins mie/miex or via mib/mibx. using an external supplied local oscillator at in/inx a converted output signal is created at the open collector output pins mo/mox. in a second configuration the rf should be connected to the pins in/inx and the pins mib/mibx/mie/miex need to be connected to an external tank circuit, thus forming for example an colpitts oscillator using the internal transistor stages. in both cases the open collector pins mo/mox need to be connected to an external supply voltage. to improve the mixer perfor- mance external resistors at mie/miex make it possible to adjust the mixer cur- rent. the rf connections to the mixer input can be single ended or balanced, capacitive or inductive. supply voltage for the mixer has to be connected to the pin vcc and to gnd. 3.4.2 oscillator / amplifier using the additional transistor stage it is possible to realize via external compo- nents an oscillator or an amplifer circuit. base ab, emitter ae and collector ac are external available.to adjust the amplifier/oscillator current using a current mirror the internal reference voltage at vref has to be connected to bref with an external resistor and bref needs to be connected to the base ab. this can be done via a resistor and/or a choke. external matching networks at the in- and output of the transistor stage will improve the amplifier performance. 3.4.3 common differential signals and symmetrical circuits are used throughout the mixer part of the ic. an internal bias driver generates supply voltage and temperature compensated reference voltages. the stb pin allows the ic to be switched in a low power mode. the pins bref,vref,stb,vcc,in,inx,and mo,mox are esd pro- tected.
