“…For a 5% power compression, the output power level drops by 0.223 dB. From Figure 3 in [8], one can find that the input power should be -6 dB or even lower than the IP1dB (input 1-dB compression point) to ensure an output power compression of less than 5%. Thus, the input 1-dB power should be higher than -66.29 dBm for the ALMA Band-1 receiver.…”

The Atacama Large Millimeter/submillimeter Array (ALMA) Band-1 receiver covers the frequency band between 35-50 GHz. An extension of up to 52 GHz is on a best-effort basis. Covering the longest wavelengths visible with ALMA, this receiver is enabling studies of dust grain evolution in proto-planetary systems probing dust grain sizes close to 1cm, and with multiple red-shifted molecular lines it will open up a new window in the high-redshift Universe. The Band-1 project has recently achieved first light and with this passed a major project milestone. We present the challenges, from initial development to prototype, to establishing the infrastructure, integration, and evaluation of 73 production receiver units, and to the final tasks to complete the project. We conclude with the initial performance and characterization of the first Band-1 receivers installed on ALMA.

“…A doubly balanced mixer (DBM) provides wide bandwidth, excellent suppression of even harmonics of 1 [4]. In addition, a DBM with diodes does not require DC consumption and achieves higher input P1dB than that of an active mixer [2,5]. The two most popular types of doubly balanced mixers (DBMs) are doubly balanced star mixers (DBSMs) and doubly balanced ring mixers (DBRMs).…”

The letter presents a high-performance doubly balanced ring mixer (DBRM) fabricated by a 0.1 µm GaAs pHEMT process that achieves ultrawide radio-frequency (RF) and intermediate frequency (IF) bandwidths. A multiple-coupled-line Marchand balun is optimized to extend the RF bandwidth. A novel structure is designed to directly extract the IF current from the RF balun without an additional IF coupler. Due to the proposed IF extraction structure, the IF bandwidth is broadened with decreased complexity. The size of the whole chip including the probe GSG pads is 0.95×0.65 mm 2 . The measured results show that the conversion loss is 7.2-11.9 dB for the RF frequency range of 35-95 GHz with an LO power level of 14 dBm and a fixed IF frequency of 1 GHz. In addition, the conversion loss is better than 12 dB for the IF frequency range from DC to 30 GHz under a fixed LO frequency. key words: ultrawide bandwidth, doubly balanced ring mixer (DBRM), Marchand balun, monolithic microwave integrated circuit (MMIC) Classification: Microwave and millimeter-wave devices, circuits, and modules

Design of a full V‐band fundamental mixer with an ultra‐wide IF from 0.01 to 22 GHz

Design of a low cost Schottky diode based single-balanced mixer (SBM) in full V-band with an ultra-wide intermediate frequency (IF) bandwidth is presented here. By loading multiple quarter-wavelength short-ended stubs at both radio frequency (RF) and local oscillator (LO) frequency on the multistage stepped impedance matching networks, a broadband grounding circuit is provided for IF signal and thus output power nulls are eliminated over an ultra-wide IF band. The hybrid network is constructed by a 3 dB branch coupler and a 90-degree delay line, which enables the required balanced outputs with equal amplitude and 180-degree phase difference. A prototype of the SBM is designed, fabricated and tested. Measured results demonstrate that, for RF and LO frequency over entire V-band, the mixer has a conversion loss from 6.8 to 11.4 dB with an ultra-wide IF range of 0.01-22 GHz.
