This 18 W asymmetrical Doherty RF power GaN amplifier is designed for cellular base station applications requiring very wide instantaneous bandwidth capability covering the frequency range of 3300 to 3800 MHz.
This part is characterized and performance is guaranteed for applications operating in the 3300 to 3800 MHz band. There is no guarantee of performance when this part is used in applications designed outside of these frequencies.
Typical Doherty Single-Carrier W-CDMA Reference Circuit Performance: VDD = 48 Vdc, IDQA = 70 mA, VGSB = –4.0 Vdc, Pout = 18 W Avg., Input Signal PAR = 9.9 dB @ 0.01% Probability on CCDF.(1)
