“…Due to the applicability of the stacked-FET [1,2,3] structure to the design of broadband RF PAs, a variety of scholars have developed broadband PAs with several typologies based on different processes such as CMOS [4,5,6], GaAs [7,8,9], and GaN [10,11,12]. Among them, GaAs is one of the most suitable mature processes for developing mid-power, high-linearity, and high-efficiency broadband PA. For typologies, the distributed amplifier has a superior bandwidth performance, while it is oversize and inefficient [11,12,13,14,15,16].…”

In this letter, a 30 MHz-3 GHz 1 W ultra-broadband stacked power amplifier (PA) fabricated in 0.25 um GaAs pHEMT technology process is presented. By inserting an RC network between the bridge-T input lossy matching network and the stacked-FET, the stability enhancement and input standing wave ratio (SWR) optimization are achieved with high frequency gain compensation. Based on the performance simulations of the stacked-PA with various normalized output load impedance, an optimal output matching method is applied, which obtains 31±1 dBm output power at 15 dBm input power, while the peak PAE achieves 60.2% at 30 MHz and the PAE larger than 35% over all of the operating frequency band. Moreover, the size of MMIC PA achieves 1.51 mm 2 with 50 Ω input and output matching.
