Biasing Considerations
The AMMC-6333 is a balanced amplier consisting of two
four stage single-ended ampliers, two Lange couplers, a
power monitoring detector, a reference detector for tem-
perature compensation, and a current mirror for the gate
biasing (Figure 17).
The recommended quiescent DC bias conditions for
optimum gain, output power, eciency, and reliability
are: Vd = 5 V with Vg set for IdQ = 230 mA. The drain bias
voltage range is from 3 to 5 V. Drain current range is from
200 mA to 350 mA. The AMMC-6333 can be biased with a
dual or single positive DC source (Figure 18).
The output power detection network provides a way to
monitor output power. The dierential voltage between
the DET_R and DET_O outputs can be correlated with the
RF power emerging from the RF output port. This voltage
is given by:
V = (VDET_R – VDET_O) – VOFS
Figure 17. AMMC-6333 schematic
Where:
VDET_R is the voltage at the DET_R port
VDET_O is a voltage at the DET_O port
VOFS is the oset voltage at zero input power
The oset voltage (VOFS) can be at each power level by
turning o the input power and measuring V. The error
due to temperature drift should be less than 0.01dB/50°C.
When VOFS is determined at a single reference tempera-
ture the drift error should be less than 0.25dB. Finally,
VOFS be characterized over a range of temperatures 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.
The RF ports are AC coupled at the RF input to the rst
stage and the RF output of the nal stage. No ground
wires are needed since ground connections are made
with plated through-holes to the backside of the device.
