Circuit description (for optimum OIP3)
Bill of Materials
Figure 6. 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 inband signal from the DC supply as shown in Figure
6. Capacitor C3 serves as an RF bypass for inband signals
while C4 helps to eliminate out the band low frequency
signals. An optional R1 may be added to de-Q any reso-
nance created between C3 and C4. Typical values range
from 2.2Ω to 10Ω . 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 ca-
pacitor (to isolate supply voltage from previous circuits) as
well as with L1, creates a filter response that remove low
frequencies signals.
