RMBA09501-58
Cellular 2 Watt Linear GaAs MMIC
Power Amplifier
ADVANCED INFORMATION
CAUTION: THIS IS AN ESD SENSITIVE DEVICE.
The following describes a procedure for evaluating the RMBA09501-58, a monolithic high efficiency power
amplifier, in a surface mount package, designed for use as a driver stage for Cellular base stations, or as the final
output stage for Micro- and Pico-Cell base stations. Figure 1 shows the package outline and the pin designations.
Figure 2 shows the functional block diagram of the packaged product. It should be noted that RMBA09501-58
requires external passive components for DC bias and RF output matching circuits. A recommended schematic
circuit is shown in Figure 3. The gate biases for the two stages of the amplifier may be set by simple resistive
voltage dividers. Figure 4 shows a typical layout of an evaluation board, corresponding to the schematic circuits of
figure 3. The following designations should be noted:
(1) Pin designations are as shown in figure 2.
(2) Vg1 and Vg2 are the Gate Voltages (negative)
applied at the pins of the package
(3) Vgg1 and Vgg2 are the negative supply voltages at
the evaluation board terminals
(4) Vd1 and Vd2 are the Drain Voltages (positive)
applied at the pins of the package
(5) Vdd1 and Vdd2 are the positive supply voltages at
the evaluation board terminals
Note: The 2 terminals of Vdd1 and Vdd2 may be tied
together.
The base of the package must be soldered on to a heat
sink for proper operation.
