Job Description

Samsung Cambridge develops world class Wi-Fi and Bluetooth IP that features in multiple chipsets for smartphones, tablets and IOT devices. We are seeking to recruit an RFIC (Radio Frequency Integrated Circuit) Systems Architect to join our RF/Analogue systems team and define our future radio systems.  The ideal candidate will have experience in delivering industry beating products in mobile communications – outperforming the competition in radio performance, power consumption and silicon area. The main role activity will be the definition of system architectures for Wi-Fi and Bluetooth radios.  You will work closely with the modem systems and radio optimisation teams who are collocated with the RFA systems team in Cambridge.  You will provide occasional technical support to the standards team.  As part of a global team the role will include communication with and occasional travel to other design centres in Korea, the US and Europe. 


  • Radio architecture definition & circuit design specifications of the circuit blocks for a full sub-system, e.g. Tx, Rx, LO, DPD loopback. 
  • The production of detailed system models for verification of circuit block specifications and verifying the circuit simulation results against system performance requirements. 
  • Documentation and presentation of specifications and system simulation results to implementation teams. 
  • Assist the radio optimisation team with silicon bring-up and root-cause debugging of technical issues, including customer, certification or regulatory issues. 

Required Skills:

  • Detailed knowledge of the architectures and line-ups for Transmit, Receive and Local Oscillator used in RFIC solutions for highly integrated Wi-Fi/BT transceiver platforms.
  • Detailed understanding of Transmit line-up analysis, including transmit power control & transmit calibration methods.  Understanding of digital pre-distortion radio requirements
  • Detailed understanding of Receiver line-up analysis, SiNaD optimisation, AGC & RSSI and Rx calibration methods. 
  • Knowledge of analogue circuit design, ideally for RF/Analogue CMOS circuits.   
  • Knowledge of radio platform architectures for mobile connectivity e.g. RFIC TRx, FEM, Filters, Switches, PMIC.
  • Good communication & team-working skills plus outstanding problem solving skills
  • Good Degree (or equivalent qualification / experience) in maths / science / electronics
  • Familiarity with modelling and specification tools for Radio Systems, e.g. Matlab

Desired Skills:
