Abstract
This paper presents the design considerations for a microstrip feedforward linearizer. The linearizer is suitable for MMIC implementation and can be adjusted using a memory circuit. A wide operating frequency, input level and temperature range is, therefore, feasible. Measured results for a 900 MHz linearizer show a 25 dB carrier to intermodulation noise improvement over a wide operating range.
