Latest Patents
One of Dow's latest patents involves a CDMA power amplifier design that operates efficiently in both low and high power modes. This innovative amplifier circuit responds to a power mode signal, improving efficiency at low power levels without compromising performance at high power levels. At low power levels, the circuit presents high impedance with suitable adjustments in the phase of the signal. Additionally, the incorporation of predistortion linearization enhances high power efficiency, while switching the predistortion linearizer OFF at low power levels results in minimal insertion loss. The design also features a bias circuit with a dual harmonic resonance filter, providing high impedance at a fundamental frequency and low impedance at a second harmonic. These characteristics are particularly advantageous, as cell phone amplifiers typically operate in low power modes most of the time, despite being designed for optimal efficiency at higher power levels.
