Description
RMPA2451B-58
2.4-2.5 GHz GaAs MMIC
Power Amplifier
PRODUCT INFORMATION
Raytheon RMPA2451B-58 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 Raytheon’s 0.25µm power PHEMT process.

Notes:
1. Notes 4, 5. At 25°C using Raytheon Test Boards.
2. Production Testing includes Gain, Output Power at 1-dB gain compression (P1dB) and Input Return Loss at Vd1 = Vd2 = +5.0V;
Vg1,Vg2 = -0.5V (nominal), adjust Vg1 and Vg2 to get Idq1 = 60 mA, Idq2 = 340 mA and at F = 2.45 GHz.
3. Two tone 3rd order Output Intermodulation products (IM3) are measured with total output power level of +25 dBm.
Other Parameters are guaranteed by Design Validation Testing (DVT).
Characteristic performance data and specifications are subject to change without notice.
