Notes:
The gain for the unmatched device in 50 ohm system is shown as the trace in black color. For a tuned circuit for a particular frequency,
it is expected that actual gain will be higher, up to the maximum stable gain. The maximum stable gain is shown in the dashed red line.
The impedance loss plots are shown from 0.05, 0.1 and 0.2 – 4.0 GHz, with markers placed in 0.2 GHz increments.

Application Circuit PC Board Layout
Circuit Board Material: Top RF layer is .014” Getek, 4 total layers (0.062” thick) for mechanical rigidity
1 oz copper, Microstrip line details: width = .026”, spacing = .026”
The silk screen markers ‘A’, ‘B’, ‘C’, etc. and ‘1’, ‘2’, ‘3’, etc. are used as placemarkers for the input and
output tuning shunt capacitors – C8, C9 and C10. The markers and vias are spaced in .050” increments.
