RMPA2451B-58
2.4-2.5 GHz GaAs MMIC
Power Amplifier
PRODUCT INFORMATION
CAUTION: THIS IS AN ESD SENSITIVE DEVICE.
The following describes the procedure for evaluating the RMPA2451B-58, a partially-matched Pseudomorphic High
Electron Mobility (PHEMT) monolithic power amplifier which has been designed for wireless applications in the 2.4
- 2.5 GHz ISM band, in a surface mount package. The package outline, along with the pin designations, is provided
as Figure 1. The functional block diagram of the packaged product is provided as Figure 2.
It should be noted that the RMPA2451B-58 requires the use of external passive components to form the DC bias
and RF output matching circuits. The schematic for a recommended DC bias / RF matching circuit is shown in
Figure 3, along with a list of the appropriate components. Figure 2 illustrates the layout of an evaluation board
based on this schematic (RMPA2451B-58-TB).
Figures 5 to 7 illustrate typical device performance. This data for various operating parameters was obtained
across the design bandwidth over a range of temperatures.
Figure 5 shows the variation in Gain and P1dB with temperature and operating frequency.
Figure 6 shows the 3rd-order intermodulation product measured at different total output power levels.
Figure 7 demonstrates the device performance under a Wideband Code Division Multiple Access (W-CDMA)
modulation scheme, the conditions of which are specified.
