PRODUCT INFORMATION
CAUTION: THIS IS AN ESD SENSITIVE DEVICE.
The following describes a procedure for evaluating the RMPA1902-58, a monolithic high efficiency power amplifier,
in a surface mount package, designed for use in Personal Communication Systems (PCS) utilizing Code Division
Multiple Access (CDMA). 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 RMPA1902-58 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 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 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
Note: The 3 terminals of Vgg1, Vgg2 and Vgg3 may
be tied together.
(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.
