r IC, TUA2007 is used here to provide real conditions on the SAW filter input side. A SAW filters symmetrical output is terminated usually by the differential amplifier of an IF-IC. Here we choose two common collector stages as buffer, the symmetric output is combined by widebandtransformer ( balun) to a practical unsymmetrical output for direct connection to a network analyzer.
The circuit Before the introduction of the switchable SAW filter type, one of a set of two separate SAW filters was switched alternately to the input of the IF amplifier. Acceptable selectivity of the filter selected ... |
