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

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.
