RFPA2013 Application Note
Product Description
The RFPA2013 is a 0.5W QFN package power amplifier specifically designed for Wireless Infrastructure applications. The
RFPA2013 is a single-stage GaAs HBT power amplifier offering ultra-linear operation at a comparably low DC power making it
ideal for next generation radios requiring high efficiency. This amplifier is ideal for GaAs Pre-Driver for Base Station Amplifiers,
PA Stage for Commercial Wireless Infrastructure, 2nd or 3rd Stage LNAs, and Class AB Operation for GSM, DCS, PCS, UMTS,
WiMAX, TD-SCDMA, and LTE Transceiver Applications. The RFPA2013 offers a low noise figure making it an excellent solution
for 2nd and 3rd stage LNAs.
The RFPA2013 is capable of operating in other bands such as 425MHz to 475MHz and 675MHz to 725MHz. Its external
matching allows for use across various radio platforms within 400MHz to 2700MHz.
The following performance data of other band application is collected at normal operation condition (room temperature and
VBIAS and VREF at 5V).
