- OK, more questions on series to parallel conversions and L-nets. Let's try this one on for size: Assume a resonant RLC circuit. The input impedance is 4600 Ohms. C is conected to ground at 7.6 pF. L

- Jon asks: Because the example given isn't resonant. 7.6pF at 28 MHz is -j747.9 ohms. In shunt with 4600 ohms, this gives a series equivalent of -j728.6 in series with 118.5 ohms. 1 microhenry is j 17

- I don't understand. The extra inductor acts as an impedance transformer. It's reactance changes with frequency and so the resulting output impedance (prior to the tank circuit) changes over frequenc

- Bandwidth on 10m. I set up the Smith Chart with the 4600 ohms as the load, and looked in from the 50 ohm end. On 10m, the 2:1 SWR Bandwidth for any particular setting of the L's and C's was less with
