Notes:
The gain for the unmatched device in 50 ohm system is shown as the trace in pink color, [DB (S (2, 1)]. 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 blue line [DB (GMAX)].
The impedance plots are shown from 0.01 – 4 GHz, with markers placed in 0.5 GHz increments.

Application Circuit PC Board Layout
Circuit Board Material: Top RF layer is .014” Getek,
є
r
= 4.0, 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, C5 and C2. The markers and vias are spaced in .050” increments.
