“…On the other hand, the X-band (8)(9)(10)(11)(12) GHz) can achieve finer resolution than the S-band, but the detection range of the target is restricted due to its high loss. Thus, a dual-band imaging system is an attractive alternative, since it can flexibly select a suitable frequency according to the situation [4].…”

A dual-band through-the-wall imaging radar receiver for a frequency-modulated continuous-wave radar system was designed and fabricated. The operating frequency bands of the receiver are S-band (2-4 GHz) and . If the target is behind a wall, wall-reflected waves are rejected by a reconfigurable Gm-C high-pass filter. The filter is designed using a high-order admittance synthesis method, and consists of transconductor circuits and capacitors. The cutoff frequency of the filter can be tuned by changing the reference current. The receiver system is fabricated on a printed circuit board using commercial devices. Measurements show 44.3 dB gain and 3.7 dB noise figure for the S-band input, and 58 dB gain and 3.02 dB noise figure for the X-band input. The cutoff frequency of the filter can be tuned from 0.7 MHz to 2.4 MHz.

“…Integrated frequency-modulated-continuous-wave (FMCW) radar transmitters and receivers at 24 GHz and higher frequencies have been the focus of the many recent studies [1][2][3][4][5][6][7][8][9][10][11][12][13]. A fully integrated transceiver, which integrates all radio frequency (RF) and microwave components, has great advantages in terms of cost, system integrity, RF signal cross-talk, and transmission loss as well as the overall power consumption.…”

“…Traditionally, III-V processes as well as SiGe technologies are utilized for the transceiver's implementations, operating at these frequencies [1][2][3][4]. However, in recent years, CMOS technologies are becoming more favorable as the rapid downscaling of CMOS processes allows the designers to implement their circuits on these technologies with less production cost and better analog-digital integrity [5][6][7][8].…”

A 24 GHz low-power transceiver is designed, fabricated, and characterized using 130 nm complementary metal-oxide semiconductor (CMOS) process. The designed transceiver is targeted for frequency-modulated-continuous-wave (FMCW) wireless local positioning. The transceiver includes four switchable receiving channels, one transmitting channel and local-oscillator generation circuitries. Several power-saving techniques are implemented, such as switch channel and adaptive mixer biasing. The design aspects of the low-power circuit blocks and integration considerations are presented in details. The integrated transceiver has a chip area of only 2.2 mm × 1.7 mm. In transmitting mode the transceiver achieves an output power of 4 dBm and phase noise of 290 dBc/Hz at 1 MHz, while consuming 75 mW power consumption under 1.5 V power supply. In switch-channel receiving mode the transceiver demonstrates 31 dB gain and 6 dB noise figure with 65 mW power consumption. The transceiver measurements compare well with the simulated results and achieve state-of-the-art performance with very low-power consumption.

“…(Bi)CMOS processes have recently been proven to be a viable platform for millimeter wave (mm-wave) transceivers [1]. To achieve a highly integrated system and to address the complex problem of delivering/accessing an mm-wave signal off the chip, a high performance antenna is required.…”
