Technical Student Intern for RF Division
Location: Chengdu

Department Description
The RF Division, is part of the Network and Computing Systems Group of Freesca
le Semiconductor. RFD develops high power discrete and IC solutions for the Ce
llular Infrastructure(GSM, W-CDMA, WiMax), CATV, Industrial-Scientific-Medical
, and Microwave/Avionics markets. Key product offerings are used in: cellular
and WiMax basestations, analog/digital broadcast television systems, cable TV
systems, industrial RF systems, as well as other applications.

Scope of Responsibilities/Expectations
Main responsibilities include the design and development of Discrete High Powe
r RF Transistors for the wireless infrastructure markets. Design work involves
low impedance transistor matching networks including integrated passives, wir
e bonds, MOSCAPs, packaging interfaces and PCB board level matching. The desig
n process uses a combination of measurement based techniques (e.g. loadpull da
ta, etc) and CAD software with the use of linear and non-linear models. The de
sign process will make use of Agilent’s ADS, 3D and planar electromagnetic si
mulation tools. The position will require for the individual to work closely w
ith device engineers, product engineers, modeling engineers and manufacturing
personnel for successful and timely product introduction. It will focus on ISM
and broadcasting market application support for global market.

Specific Knowledge/Skills
Candidate will hold a minimum of a BS degree, MS preferred in electrical engin
eering, physics or related technical field and have a minimum of 1 to 2 years
direct experience in designing high-power RF transistor internal-matching netw
orks 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 bac
kground on Microwave and RF engineering with an emphasis on several of the fol
lowing areas:
• Hands-on experience with board level tuning and optimization of matchi
ng networks.
• Microwave measurement techniques (S-parameters, loadpull setups, VNA c
alibration techniques, spectrum analyzers, power meters, etc).
• Understanding and development of advanced RF/microwave measurement tec
hniques
• Working knowledge with Agilent's Advanced Design System (ADS) , Ansoft
's High Frequency Structure Simulator (HFSS) and planar electromagnetic solver
s (Sonnet's Em and/or Agilent's Momentum)
• Solid understanding concerning circuit instability and strategies to r
esolve them.
• ISM & Broadcasting products experience will be the plus.
• Strong communication skills
