In certain implementations, a packaged RF amplifier includes a first bipolar transistor including a base electrically connected to an RF input pin and a collector electrically connected to an RF output pin, and a second bipolar transistor including a base electrically connected to an emitter of the first bipolar transistor and a collector electrically connected to the RF output pin. The packaged RF amplifier further includes a first bias circuit electrically connected between the base of the first bipolar transistor and the RF output pin, a second bias circuit electrically connected between the base of the first bipolar transistor and a power low pin, an inductor implemented at least partly by a bond wire, and a third bias circuit electrically connected in series with the inductor between the base of the second bipolar transistor and the power low pin."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and methods for radio frequency amplifiers","description":"Apparatus and methods for radio frequency (RF) amplifiers are disclosed herein.
