AMMP-6425 Application and Usage
Recommended quiescent DC bias condition for optimum
power and linearity performances is Vdd=5 volts with Vg
(-1.1V) set for Idq=650 mA. Minor improvements in per-
formance are possible depending on the application.
The drain bias voltage range is 3 to 5V. A single DC gate
supply connected to Vgg will bias all gain stages. Muting
can be accomplished by setting Vgg to the pinch-o
voltage Vp.
A simplied schematic for the AMMP6425 MMIC die is
shown in Figure 12. The MMIC die contains ESD and over
voltage protection diodes for Vg, and Vdd terminals.
The package diagram for the recommended assembly
is shown in Figure 13. In nalized package form, ESD
diodes protect all possible ESD or over voltage damages
between Vgg and ground, Vgg and Vdd, Vdd and ground.
Typical ESD diode current versus diode voltage for 11-
connected diodes in series is shown in Figure 14. Under
the recommended DC quiescent biasing condition at
Vds=5V, Ids=650mA, Vgg=-1V, typical gate terminal
current is approximately 0.3mA. If an active biasing
technique is selected for the AMMP6425 MMIC PA DC
biasing, the active biasing circuit must have more than
10-times higher internal current that the gate terminal
current.
An optional output power detector network is also
provided. The dierential voltage between the Det-Ref
and Det-Out pads can be correlated with the RF power

emerging from the RF output port. The detected voltage
is given by :
where Vref is the voltage at the DET_R port, Vdet is a
voltage at the DET_0 port, Vofs and is the zero-input-
power oset voltage.
There are three methods to calculate Vofs :
1. Vofs can
be
measured
before
each
detector
measurement (by removing or switching o the
power source and measuring Vref - Vdet). This method
gives an error due to temperature drift of less than
0.01dB/50°C.
2. Vofs can be measured at a single reference
temperature. The drift error will be less than 0.25dB.
3. Vofs can either be characterized over temperature and
stored in a lookup table, or it can be measured at two
temperatures and a linear t used to calculate Vofs at
any temperature. This method gives an error close to
the method #1.
The RF ports are AC coupled at the RF input to the rst
stage and the RF output of the nal stage. No ground
wired are needed since ground connections are made
with plated through-holes to the backside of the device.
