<p>An amplifier has a first transistor, a second transistor, a third transistor and a fourth transistor, a first transformation network having first and second grounds and a second transformation network having third and fourth grounds. The amplifier has a collector of the first transistor operatively connected to a base of the third transistor by the first transformation network, a collector of the second transistor operatively connected to a base of the fourth transistor by the second transformation network, the first ground and the third ground are electrically connected to each other, the second ground and the fourth ground are electrically connected to each other, the emitters of the first and of the second transistors are electrically connected to the first ground and the third ground, and the second ground and the fourth ground are electrically connected to the emitters of the third and of the fourth transistors.</p> |
