Appeal No. 95-3742

series trimming stubs could not
be used.
Appellant argues (Brief, page 3) that the trimming stub
in admitted prior art Figure 3 is in series with the
microstrip line resonator, and that it would be “impossible to
connect one end of the microstrip line to ground.” With
respect to Stajcer, appellant argues (Brief, page 3 and 4)
that “[t]he device of Stajcer is not a voltage controlled
oscillator,” and that:
As shown in Fig. 2 of Stajcer,
tuning pads 28 are provided alongside
a low-impedance transformer including
metallization 24. This low-impedance
transformer is not provided as a
microstrip line resonator for
adjusting an oscillation frequency,
but is instead provided together with
open-circuited microstrip stub 26 for
matching an output of the FET relative
to a 50-ohm output transmission line.
Accordingly, tuning pads 28 have no
role in adjusting an oscillation
frequency, but instead are provided
for matching the 50-ohm output
transmission line to maximize the
output signal.
Appellant then concludes (Brief, pages 4 and 5) that:
As explained above, Stajcer’s
tuning pads 28 are provided for
matching the output impedance, but not
for adjusting the frequency. Thus,
the combination suggested in the Final
