PCS CDMA GaAs MMIC
Power Amplifier
PRODUCT INFORMATION
CAUTION: THIS IS AN ESD SENSITIVE DEVICE.
The following describes a procedure for evaluating the RMPA1901-53, 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 2 shows the functional block diagram of the packaged product. Figure 1 shows
the package outline and the pin designations. It should be noted that RMPA1901-53 requires external passive
components for DC bias and RF output matching circuits. A recommended schematic of circuits is shown in Figure
3. The gate biases for the three stages of the amplifier are set by simple resistive voltage dividers. Potentiometers
R1 to R3 are used to set the required quiescent currents of the amplifier stages. Figure 4 shows a typical layout of
an evaluation board, corresponding to the schematic circuits of figure 3. The following 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, Vgg2 and Vgg3 are the negative supply
voltages at the evaluation board terminals
(4) Vd1, Vd2 and Vd3 are the Drain Voltages (positive)
applied at the pins of the package
(5) Vdd1, Vdd2 and Vdd3 are the positive supply
voltages at the evaluation board terminals
