Abstract
A 5-10-GHz, 14-W amplifier has been developed. It utilizes a multisectional maximally flat impedance transformer whose length is designed to become a quarter wavelength at the highest frequency of the design band to achieve flat gain and flat power response over a wide bandwidth. Using this transformer, the amplifier has achieved a linear gain of 7+or-1 dB, a 1-dB compressed power of 41.5+or-0.8 dBm, and a power-added efficiency of greater than 25% over 5-10 GHz.<>
