“…K A-BAND is used for satellite communications and highresolution, close-range targeting radars aboard military airplanes [1]- [3]. It is desirable to employ high-level modulation schemes such as multi-level quadrature amplitude modulation (M-QAM), multi-level phase shift keying (M-PSK) to achieve high data rate communications, which require the receiver front-end to have high conversion gains and low noise figures [4].…”

A compact, high-gain, and low-noise Ka band HTS Josephson junction-based receiver front-end module for wireless communication is presented in this paper. The front-end module consists of biasing circuits, a semiconductor low-noise amplifier, and a monolithic HTS circuit consisting of an Josephson mixer, bandpass and lowpass filters. The semiconductor LNA in the first stage is applied to achieve a low noise figure of the whole front-end module. Integration of the Josephson mixer with a number of HTS passive components on a single chip improves the coupling efficiency and reduces the connection losses between the components. The total dimension of the packaged front-end module is below 25 mm × 20 mm × 15 mm, which is very compact. Measurement result shows that the front-end module has an overall conversion gain around 40 dB, and a low noise figure close to 0 dB with an LO driving power around −38 dBm at 40 K.Index Terms-High temperature superconductor (HTS), Josephson mixer, low loss, low noise, monolithic, receiver front-end.

“…Additionally, the challenge for a ring DBM design is IF signal extraction. Previous ring DBM designs require an additional extraction circuit for the IF port [5][6][7] to enhance RFto-IF isolation. These methods may still cause layout complications, making the integration of the mixer in a low-cost and compact system more difficult.…”

A Broadband Doubly Balanced Monolithic Ring Mixer With a Compact Intermediate Frequency (If) Extraction

Abstract-To meet the requirements for broadband operation, high port-to-port isolation, and miniature chip area, a doubly balanced monolithic microwave ring mixer with an advanced IF extraction fabricated using 0.15 µm GaAs pHEMT process is presented. A miniature Marchand-like spiral balun with low-pass filter is used to extract IF signals and maintain balun performance simultaneously. The low-pass filter can filter out both the RF and LO signals. This miniaturized mixer design can mitigate layout complexity, improve port-to-port isolations suitable for ultra-broadband Ku-, K-, and Kaband applications. Subsequently, the LO/RF-to-IF isolations are greater than 43.2 and 32 dB from 11 to 40 GHz, respectively. The LO-to-RF isolation is between 26.9 and 50.7 dB within the same swept range. The conversion loss is 7.2-12.4 dB within the operating bandwidth.

“…The bandwidth, which is 16 to 40 GHz, is the broadest reported; the chip size is relatively small; the LO-to-RF isolation is very good; and the input P1 dB, which is 14 dBm, is the highest linearity reported. Yu's mixing diodes, with a very low turn on voltage of 0.15 V at 1 mA, requires lower LO power, but the input P1 dB is relatively smaller [6]. The proposed mixer with high broadband, small chip size and low LO driver shows good trade-off with other performances.…”

A broadband doubly balanced monolithic ring mixer with a new intermediate frequency (IF) signal extraction method implemented by 0.15 m pHEMT process is presented. The hybrid couplers of the proposed mixer consist of multiple coupled lines and fourfold coupled line Marchand baluns. The use of multiple coupled lines leads to a die size less than 1 1 mm 2 and improves the bandwidth of the mixer. The novel fourfold coupled line allows the extraction of the IF signal directly without any extra low pass filter circuits. The mixer exhibited 8-13 dB conversion loss, high radio frequency/local oscillation isolation of 35-50 dB over 16-40 GHz and an input 1-dB compression point of 14 dBm. Index Terms-Doubly balanced ring mixer, K-band, Ka-band, monolithic microwave integrated circuit (MMIC), pHEMT.
