'''1.1 What is the difference between the two ICs?'''
 
−
 
 
−
:Both chips include send and receive antennas in a standard QFN package. The main difference lies in the antenna designs. While the [[TRX_120_001]] uses tiny patch antennas on a separate "PCB" within the IC's package, the [[TRA_120_002]] has its dipole antennas already included on the chip die. Therefore the packages are different in size and beam characteristics differ.
 
−
 
 
−
'''1.2 What is the minimum range or is there a blind spot?'''
 
−
 
 
−
:The minimum range is dependent on the selected bandwidth. 1 GHz bandwidth works from about 30 cm, 6 GHz works from about 7 cm.
 
−
 
 
−
'''1.3 Can something be detected below the minimum range?'''
 
−
 
 
−
:Going below the bandwidth-dictated minimum range leads to an increased DC-offset in the FFT output. It could be used to detect "something is nearby" but this is very application-specific.
 
−
 
 
−
'''1.4 What is the resolution of the chips?'''
 
−
 
 
−
:We define the resolution as the ability to separate two objects in range. The resolution is only dependent on the selected bandwidth. With 1 GHz bandwidth the resolution is 15 cm, 6 GHz equals to 2,5 cm resolution. In practice, target recognition works from twice the resolution.

The RFE is an integrated transceiver circuit for the 122-GHz ISM band with antennas in the QFN 8x8 package. It includes a low-noise amplifier (LNA), quadrature mixers, a poly-phase filter, a voltage controlled oscillator, divide-by-32 outputs, and transmit and receive antennas. The RF signal from the oscillator is directed to the RX path via buffer circuits. The RX signal is amplified by the LNA and converted to the baseband by two mixers with a quadrature local oscillator (LO). The 120-GHz LO has four analog tuning inputs with different tuning ranges and tuning slopes. The tuning inputs can be combined to obtain a wide frequency tuning range. The analog tuning inputs together with integrated frequency divider and external fractional-N PLL can be used for frequency modulated continuous wave (FMCW) radar operation. With fixed oscillator frequency it can be used in continuous wave (CW) mode. Other modulation schemes are possible as well by utilizing analog tuning inputs. The IC is fabricated in SG13S SiGe BiCMOS technology [https://www.ihp-microelectronics.com/en/services/mpw-prototyping/sigec-bicmos-technologies.html].
