for impedance matching or for
DC blocking capacitors. For noise
figure sensitive applications, the
use of PTFE/glass dielectric
materials may be warranted to
minimize transmission line losses
at the amplifier input.
Higher Bias Voltages
While the MGA-87563 is designed
for use in +3 volt battery powered
applications, the internal bias
regulation circuitry allows it to be
easily operated with any power
supply voltage from +2.7 to
5 volts. Figure 15 shows an
increase of approximately 1 dB in
the associated gain with +5 volts
applied. The P_1dB output power
(Figure 17) is also higher by
about 1 dBm. The effect of higher
V_dd on noise figure is negligible as
indicated in Figure 16.
