RMBA09501-58 - Cellular 2 Watt Linear GaAs
RF Components MMIC Power Amplifier
ADVANCED INFORMATION
Application
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.
The RMBA09501-58 requires external passive components for DC bias and RF input and output
matching circuits as shown in Figure 3 and the Parts List. 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.
