An approach to design and manufacture a limiter, capable of adjusting output signal level for X-band radars
Keywords:
Limiter, Variable attenuation limiter, PIN diodeAbstract
This paper presents a study, design, and manufacture of a power limiter capable of adjusting the output signal level applied to the X-band radar receiver. The limiter is designed based on 2 stages of PIN diodes impedance matching on the micro-strip line is capable of withstanding up to 59dBm of input power and limiting the highest output power to 19dBm to protect the receiver while also being able to attenuate the output signal in 032dB range to enhance dynamic receiver range. Calculations can be performed at the appropriate frequency range for the required application.
