About Ultra-Wide-Band (UWB):
Ultra-Wide-Band (UWB) is an emerging high growth Connectivity technology. Short pulses <3-4ns is used to communicate between a Key Fob and a Car for secure ranging. The short nature of the pulse along with very low duty cycle and advanced data encryption makes it a secure communication approach. Radio operates around microwave frequency band of 7-10GHz and uses 500MHz bandwidth. UWB technology is growing exponentially with Cell Phone Manufacturers such as Apple and Samsung integrating it in the phone and Car OEM’s such as BMW, BYD, Tesla et al integrating UWB based anchors inside car. Besides communication, UWB is perfect for sensing/radar applications. For example, in child safety where UWB based Radar can detect periodic muscle movement such as breathing or general human presence. UWB Radar can also detect various movements around the Car such as kick to open the trunk, an intruder or an occupied seat.
About RF Transceiver Group in Connectivity:
Texas Instruments RF Connectivity group is expanding their RF Transceiver Design group. This group develops cutting edge RF Transceiver products (+MCU integrated) for Wireless-LAN (WIFI) and Ultra-Wideband Systems (UWB). The candidate will join in the UWB Design group. Candidate gets to experience Block Architecture Phase, Concept Design and take the design through the various design phases such as Schematic, Layout, Extracted simulations and Test and Verification. The role is primarily in Analog/RF class of circuit design to meet the overall System & Product requirements. The typical blocks include RF blocks such as LNA, TA, Down-conversion Mixers, Base-band filters, High Speed ADC to send data to the Modem. Reverse Chain namely for Transmitter, starting from DAC, Base-band filter, Up-conversion mixer and Power Amplifier stages to drive the TX Pin. LO system design including Chrystal Oscillator, integer/fractional PLL and LO Distribution systems. Various Calibration modules (AGC, PDET, Gain, Offset, IQMM, etc) to calibrate the Transceiver chain is part of the design. Low Current Mode and Complex Power Management to operate at low LDO input voltage etc. The Design Engineer in RF Connectivity gets introduced to a Holistic view of the product including, Radio Silicon Design, Packaging and PCB and solution design.
