The flux transformer does not provide the large bandwidth typical of the output transmission-line transformer shown in Figure 3, but it usually performs well over smaller bandwidths, especially when tuned with shunt capacitors (not shown). The flux transformer design eliminates DC blocking capacitors and is attrac- tive in rugged applications where the amplifier output is subjected to ESD events and other forms of transient electrical overstress that do not pass through a typical RF flux transformer such as the MABAES0061. Figure 9d shows a discrete LC balun suitable for bandwidths of approximately 15% to 30%. Larger bandwidths are difficult to achieve with the number of components shown, and smaller bandwidths are often limited by component tolerance effects. Despite these limitations, the discrete LC balun can be a cost effective output circuit solution. At resonance, the tuned circuit produces an impedance transformation along with the differential-to-single-ended conversion. DC Coupled Operation The LTC6412 is intended for AC-coupled operation. The translation between the fixed input DC common mode voltage and higher open-collector output DC bias point makes it impractical to use in DC-coupled applications. |
