A schematic diagram of the application circuit is shown
in Figure 15. DC blocking capacitors (C1 and C2) are used
at the input and output of the MMIC to isolate the de-
vice from adjacent circuits. While the input terminal of
the MGA-82563 is at ground potential, it is not a current
sink. If the input is connected to a preceding stage that
has a voltage present, the use of the DC blocking capaci-
tor (C1) is required.

Figure 15. Schematic Diagram.
DC bias is applied to the MGA-82563 through the RF
Output pin. An inductor (RFC), or length of high imped-
ance transmission line (preferably O/4 at the band cen-
ter), is used to isolate the RF from the DC supply.
The power supply is bypassed to ground with capacitor
C3 to keep RF off of the DC lines and to prevent gain dips
or peaks in the response of the amplifier.
An additional bypass capacitor, C4, may be added to the
bias line near the V
feedback through bias lines that could cause oscillation.
C4 will not normally be needed unless several stages are
cascaded using a common power supply.

When multiple bypass capacitors are used, consideration
should be given to potential resonances. It is important
to ensure that the capacitors when combined with ad-
ditional parasitic L’s and C’s on the circuit board do not
form resonant circuits. The addition of a small value re-
sistor in the bias supply line between bypass capacitors
will often “de-Q” the bias circuit and eliminate the effect
of a resonance.
The value of the DC blocking and RF bypass capacitors
(C1 - C3) should be chosen to provide a small reactance
(typically <5 ohms) at the lowest operating frequency.
The reactance of the RF choke (RFC) should be high (e.g.,
several hundred ohms) at the lowest frequency of opera-
tion.
The MGA-82563’s response at low frequencies is limited
to approximately 100 MHz by the size of capacitors inte-
grated on the MMIC chip.
The input and output of the MGA-82563 are well matched
to 50 Ω. Without external matching elements, the in-
put VSWR of the MGA-82563 is ≤ 2.0:1 from 300 MHz
to 6 GHz and the Output VSWR is ≤ 1.6:1 from 100 MHz
through 6 GHz.
For applications requiring minimum noise figure (NF
improvement over a 50Ω match is possible by matching the
signal input to the optimum noise match impedance, *
specified in the “Typical Noise Parameters” table. The data
in the table shows the noise match to be very close to 50Ω.
The completed application amplifier with all compo-
nents and SMA connectors is shown in Figure 16.
