RMPA2451-58
# 425430398 2.4-2.5 GHz GaAs MMIC
Power Amplifier
PRODUCT INFORMATION
Application
Information
CAUTION: THIS IS AN ESD SENSITIVE DEVICE.
The following describes the procedure for evaluating the RMPA2451-58, a partially-matched 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 RMPA2451-58 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 4 illustrates the
layout of an evaluation board based on this schematic (RMPA2451-58-TB).
Figures 5 and 6 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.
