RF-ENGR in Chengdu:
Department Description        The RF Division (RFD) is the global leader for RF power semiconductor solutions for wireless infrastructure equipment.The role of RFD design team is responsible for the design of high power RF LDMOS and GaAs discretes, RFIC’s, and modules for wireless infrastructure applications.

Scope of Responsibilities/Expectations        Main responsibilities include the design and development of Discrete High Power RF Transistors for the wireless infrastructure markets. Design work involves low impedance transistor matching networks including integrated passives, wire bonds, MOSCAPs, packaging interfaces and PCB board level matching. The design process uses a combination of measurement based techniques (e.g. loadpull data, etc) and CAD software with the use of linear and non-linear models. The design process will make use of Agilent’s ADS, 3D and planar electromagnetic simulation tools. The position will require for the individual to work closely with device engineers, product engineers, modeling engineers and manufacturing personnel for successful and timely product introduction.    
           
Specific Knowledge/Skills        Candidate will hold a minimum of a MS degree in microwave,electrical engineering, physics or related technical field and have a minimum of 1 to 2 years direct experience in designing high-power RF transistor internal-matching networks using LDMOS or GaAs HFET technologies, corresponding to devices with more than 60W output power at 2 GHz and above. The engineer must have a strong background on Microwave and RF engineering with an emphasis on several of the following areas:
• Hands-on experience with board level tuning and optimization of matching networks.
• Microwave measurement techniques (S-parameters, loadpull setups, VNA calibration techniques, spectrum analyzers, power meters, etc).
• Understanding and development of advanced RF/microwave measurement techniques
• Working knowledge with Agilent's Advanced Design System (ADS) , Ansoft's High Frequency Structure Simulator (HFSS) and planar electromagnetic solvers (Sonnet's Em and/or Agilent's Momentum)
• Solid understanding concerning circuit instability and strategies to resolve them.
• Strong communication skills
