RMPA5251  
4.90–5.85 GHz InGaP HBT Linear Power Amplifier  
• 2.5% EVM at 18.0dBm modulated power out  
General Description  
• 3.3V single positive supply operation  
• Adjustable bias current operation  
The RMPA5251 power amplifier is designed for high  
performance WLAN applications in the 4.9 to 5.35 and 5.15  
to 5.85 GHz frequency bands. The low profile 16 pin 3 x 3  
x 0.9 mm package with internal matching on both input and  
output to 50minimizes next level PCB space and allows  
for simplified integration. The on-chip detector provides  
power sensing capability while the logic control provides  
power saving shutdown options. The PA’s low power  
consumption and excellent linearity are achieved using our  
InGaP Heterojunction Bipolar Transistor (HBT) technology.  
• Two power saving shutdown options (bias and logic  
control)  
• Integrated power detector with >18dB dynamic range  
• Low profile 16 pin 3 x 3 x 0.9 mm standard QFN leadless  
package  
• Internally matched to 50Ω  
Device  
• Minimal external components  
Features  
• Optimized for use in IEEE 802.11a  
WLAN applications  
• 4.9 to 5.85 GHz Operation  
• 27dB small signal gain  
• 26dBm output power @ 1dB compression
