Designers are required to evaluate trade-offs between performance and cost while selecting key components such as power amplifiers. Choose a power amplifier pair with factory-matched amplitude and phase characteristics. Use amplifiers that have good linearity and high linearity robustness. To achieve the lowest total ownership cost, on-chip power detectors should exhibit dynamic range, sensitivity, decibel-wise linearization, and temperature robustness. A matched power housed in a single package provides a more-compact solution and saves 50 percent space and cost compared with design using separate power amplifiers. Use digital control with robust performance over the operating temperature range.
