OK. So I can't get there from here. But can I at least assume the inductance from VCC to the output is about 64nH + 26.4nH = 90.4nH, (see below . I miscalculated previously)? At 433MHz that would be about 246ohm. Shouldn't that be close to the output impedance?
The schematic I attached doesn't indicate the correct values. I measured the dimensions.
L2 = 0.0640 uH (diam 4mm, length 3.2mm, turns 4.5) approx.
L1 = 0.0264 uH (diam 4mm, length 5.4mm, turns 2.5) approx.
