A.1 Matching Network
The
matching circuit
may be a 50 Ohm / 300 Ohmbalun transformer(figure 2), but a more economical
solution is a tuned match as shown below. A single 10nH inductor is optimal in cost, but may not meet
the users tolerance requirements over spreads of silicon and pcb material, as it has only around 1pF
tuning capacitance( 2pF in serieswith 2pF inside the package).
The first example (figure 3) increases the capacitance with a discrete capacitor, and uses a lower
inductance value. Both examples assume that the ceramic filter is dc blocking, both input to output, and
output to ground.
The second (figure 4) example allows optimum matching by rationing the capacitors appropriately to
achieve voltage gain commensurate with the impedance translation. While it has a higher component
count, it is the versionmost tolerant of componentvariations and boardcapacitance.
