I'm a Ph.D. RF and Microwave Design engineer with more than 20 years of experience. I have designed every circuit in the radio except the baseband. My Ph.D., Master and Bachelor's Degrees are in RF circuit design. I have designed many RF circuits, such as mixers, Voltage Controlled Oscillators (VCO), Pre-driver, Driver Power Amplifier (PA), Final PA, Power controllers, couplers, Antenna switches, harmonic filters, Antenna, pre-selector filters, Low Noise Amplifiers (LNA), post-selector, Wilkinson power combiner, power dividers, and envelope detector. Most of my RF design experience was gained from my working experience at Motorola and my studies. Keysight Technologies awarded an accreditation called "Keysight Certified Expert" by recognizing my expertise in RF design. Engineers who have acquired a depth of theoretical and practical knowledge in applying Keysight EDA tools for successful product design and modeling will be awarded "Keysight Certified Expert." Other than me, only 87 people in the world have received this award. I'm also an embedded system hardware design engineer. I have designed embedded system hardware for many products, including a product called LEAP. I did my PhD, Master's, and Bachelor's degrees at the University of Malaya and the University of Science Malaysia, respectively. My research interest is designing wideband RF circuits, including Pas, LNAs, and VCOs.
