“…Since the baseband frequency of the FMCW radar is usually over several hundred kHz due to the chirping, it does not need large DC-decoupling capacitors, unlike Doppler radar. However, FMCW radar does require a chirp generator, which is implemented by a digital direct synthesizer (DDS) or a phase-locked loop (PLL) as shown in Figure 1(b) [13]- [16]. Furthermore, a range compensation filter, known as 1/R 4 filter is needed in the baseband to prevent the receiver from saturating when detecting nearby objects.…”

In this paper, a fully-integrated dual-mode X-band radar transceiver that supports Doppler radar and frequency modulated continuous wave (FMCW) radar is proposed. To remove large off-chip DCblocking capacitors in the Doppler mode, the double-conversion technique and local oscillator (LO) chopping technique are introduced. These techniques remove the DC offset and makes the transceiver more robust to the TX to RX leakage. In addition, they also improve the noise figure (NF) by filtering out 1/f noise of the analog baseband. The FMCW radar is realized using a direct-conversion receiver and a chirp generator. The chirp generator consists of a frequency sweep generator (FSG) and a fractional-N phaselocked loop (PLL). All the analog baseband components including a programable gain amplifiers (PGA) and 1/R 4 range compensation filters are integrated on the chip as well as a bandgap and low-dropout regulators. The operating frequency is from 9.7 to 12.3 GHz, which consumes 216 mW in Doppler mode and 201.6 mW in FMCW mode from a 1.2-V supply voltage. The maximum chirp bandwidth is 750 MHz and the maximum receiver gain is 76 dB with 6-dB gain step. The chip size of the transceiver is 7.68 mm 2 including all the pads.

“…With the fast development of the monolithic microwave integrated circuit (MMIC) technology, a number of chip-based radars have been demonstrated. [2][3][4][5][6] For radar imaging, a waveform with a large bandwidth is usually required to achieve a high resolution because the range resolution is inversely proportional to the bandwidth. However, it is challenging for electronic chip-based radars to generate and process broadband waveforms especially in the Ka band or lower.…”

Radar is the only sensor that can realize target imaging at all time and all weather, which would be a key technical enabler for future intelligent society. Poor resolution and large size are the two critical issues for radar to gain ground in civil applications. Conventional electronic radars are difficult to address due to both issues, especially in the Ka band or lower. In this work, a chip-based microwave-photonic radar based on silicon photonic platform, which can implement high-resolution imaging with very small footprint, is proposed and experimentally demonstrated. Both the wideband signal generator and the de-chirp receiver are integrated on the chip. A broadband microwave-photonic imaging radar occupying the full Ku band is experimentally established. A high-precision range measurement with a resolution of 2.7 cm and an error of less than 2.75 mm is obtained. Inverse synthetic aperture imaging of multiple targets with complex profiles is also implemented.

“…Typically, to improve the image rejection ratio, a surface acoustic wave (SAW) filter can be used in front of the mixer, resulting in a bulky and high cost solution. Considering the high integration level and image rejection requirements, the RF transceiver can be realized with Hartley or Weaver architectures [4] [5]. However, given the mismatch issues, in these architectures the image rejection performance is still limited.…”

For satellite communication applications, this paper presents an image rejection Ku-band low noise amplifier (LNA) in a 65-nm CMOS process for the Hartley receiver architecture. To achieve high input/output linearity performance, the inductive source degenerated cascode and the capacitive neutralized common-source (CS) amplifier topologies are used in the LNA input and output stages, respectively. To achieve wideband input return loss, the minimum noise figure and high gain performance simultaneously, the inductive source degenerated cascode amplifier is co-designed with the fourth order input impedance matching network. For the image rejection purpose, a bridged-tee band-stop filter is proposed. The measurements show the LNA achieves 14.3-to-18.3 GHz 3 dB bandwidth with 17-to-20 dB power gain, 3.5to-4 dB noise figure, 17-to-37 dB image rejection and-5 dBm IIP3. Including all pads, the chip occupies a silicon area of 1360 × 450 μm 2 and consumes 72 mW DC power. INDEX TERMS CMOS, Ku-band, low noise amplifier (LNA), band-stop filter (BSF), image rejection.
