AbstractIn this paper, an ultra wide-band single balanced diode mixer based on multi-section coupled line balun is presented. It is important in applications such as microwave imaging, military and civilian radars, wireless communication and microwave instrumentation. The proposed mixer is simulated in ADS software with Local Oscillator (LO) power level ranges from 3 to 17 dBm, a fixed Radio Frequency (RF) power level of -10 dBm and an Intermediate Frequency (IF) input frequency of 100 MHz. The simulated results showed that the conversion loss is greater than -15 dB for RF frequency from 3 to 10 GHz.
