The following describes a procedure for evaluating the RMBA19500A-58, a monolithic high efficiency
power amplifier, in a surface mount package, designed for use as a driver stage for PCS1900 Base
station or as the final output stage for Micro- and Pico-Cell base stations. Figure 1 shows the
package outline and the pin designations.
packaged product. The RMBA19500A-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 three 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, Vg2, and Vg3 are the Gate Voltages (negative) applied at the pins of the package.
(3) Vgg1, 2, and Vgg3 are the negative supply voltages at the evaluation board terminals (Vg1 and
Vg2 are tied together).
(4) Vd1, Vd2, and Vd3 are the Drain Voltages (positive) applied at the pins of the package.
(5) Vdd is the positive supply voltage at the evaluation board terminal (Vd1, Vd2, and Vd3 are tied
together).
Note: The base of the package must be soldered on to a heat sink for proper operation.
