RMPA2451
2.4–2.5 GHz GaAs MMIC Power Amplifier
General Description
Fairchild Semiconductor’s RMPA2451 is a partially
matched monolithic power amplifier in a surface mount
package for use in wireless applications in the 2.4 to 2.5
GHz ISM frequency band. The amplifier may be biased for
linear, class AB or class F for high efficiency applications.
External matching components are required to optimize the
RF performance. The MMIC chip design utilizes our
0.25µm power Pseudomorphic High Electron Mobility
(PHEMT) process.
Features
• 38% power added efficiency
• 29dBm typical output power
• Small package outline: 0.28" x 0.28" x 0.07"
• Low power mode: 0 dBm
