Figure 34. Demoboard and application circuit components table for Optimum OIP3
To bias the MGA-53589, a +5V supply is connected to the
output pin thru an inductor labeled as L2; which isolates
the in-band signal from the DC supply as shown in Figure
34. Capacitor C3 serves as an RF bypass for in-band signals
while C4 helps to eliminate out the band low frequency
signals.AnoptionalR1maybeaddedtode-Qanyresonance
created between C3 and C4.Typical values range from 2.2
to 10
Ω. A DC blocking capacitor C2, is used at the output
of the MMIC to isolate the supply voltage from succeeding
circuits. L3 can be added to improve the circuits ESD as well
as providing a better filtering output response. On its input,
the C1 acts as a DC blocking capacitor (to isolate supply
voltage from previous circuits) as well as with L1, creates a
filter response that remove low frequencies signals.
