The RMPA0913C-58 is a monolithic high efficiency power amplifier for AMPS/CDMA dual mode applications in the 824 to 849 MHz frequency band. Performance parameters may be slightly adjusted by “tweaking” off-chip matching components. The amplifier circuit design is a single ended configuration that utilizes harmonic tuning for increased power added efficiency and linearity.The device uses Raytheon’s Pseudomorphic High Electron Mobility Transistor (pHEMT) process.

Package Information
CAUTION: THIS IS AN ESD SENSITIVE DEVICE.
The following describes a procedure for evaluating the Raytheon RMPA0913C-58, a monolithic high efficiency power amplifier, in a surface mount package, designed for use in the AMPS/CDMA dual mode portable phones. Figure 1 shows the package outline and pin designations. Figure 2 shows the functional block diagram of the packaged product. It should be noted that the amplifier requires external passive components for DC bias and RF input and output matching circuits. A recommended schematic is shown in figure 3. The gate biases for the two stages of the amplifier are set by simple on-chip circuits. Figure 4 shows a typical layout of an evaluation board (RMPA0913C-58-TB), corresponding to the schematic circuit of figure 3. The following should be noted:
(1) Pin designations and their functions are as shown
in figure 1 and Table 1.
(2) Vg1, Vg2 are denoted as the Gate Voltages
(negative) applied at the pins of the package
(4) Vd1, Vd2 are denoted as the Drain Voltages
(positive) applied at the pins of the package
(5) Vdd1, Vdd2 are denoted as the positive supply
voltages at the evaluation board terminals
(3) Vgg1, Vgg2 are denoted as the negative supply
voltages at the evaluation board terminals
Note: The two drain voltages are tied to the same terminal denoted as Vdd on the evaluation board
