A 272–341-GHz Integrated Amplifier-Frequency-Doubler Chain in 65-nm CMOS
This letter presents a 300 GHz wide-band amplifier-frequency-doubler chain (AFDC) in 65-nm CMOS. A novel combination of series and stub transmission lines with a large DC blocking capacitor achieves superior broadband impedance matching at the output of the frequency doubler with 70 GHz bandwidth and 3.8 dB conversion gain. This AFDC outperforms alternative approaches, and…
A 240-GHz 4-TX 4-RX 2-D-MIMO FMCW Radar Transceiver in 130-nm SiGe BiCMOS
A 240-GHz 4-transmitter (TX) 4-receiver (RX) 2-D multiple-input–multiple-output (MIMO) frequency-modulated continuous-wave (FMCW) radar transceiver was designed in a 130-nm SiGe bipolar CMOS (BiCMOS) technology with fT/fmax of 250/370 GHz using patch antennas on a single 4.032×4.032 mm2 chip. The differential RF inputs, located at the emitters of the direct conversion mixer quad transistors of each…
Tunable Wideband High-Order Active Analog Delays With High Delay-Bandwidth Product
This letter describes analog delays based on wideband, high-order, tunable active all-pass filters (APFs) with poles and zeros prescribed by the Padé approximation. The number of inductors in the n th-order APF does not exceed ⌊n/2⌋ for a compact area, low insertion loss, and wide bandwidth. Delay tuning is accomplished via two control lines. The…
About the journal

The IEEE Microwave and Wireless Technology Letters (MWTL) (formerly IEEE Microwave and Wireless Components Letters (MWCL)) is published monthly with the purpose of providing short papers (up to 4 pages; 3 pages of text plus up to 1 page of references) of original and significant contributions relevant to all aspects of microwave/millimeter-wave technology, with emphasis on devices, components, circuits, guided wave structures, systems and applications covering the frequency spectrum from microwave and beyond, including submillimeter-waves and infrared.

The MWTL is the preeminent publication of short papers concerning RF and microwave technology, with an acceptance rate of 25%. The median publishing time from submission to publication is 16 weeks.

The Letters are available to digital subscribers through IEEE Xplore.

Authors interested in submitting a manuscript for publication in MWTL should first read the Information for Authors page for the Letters. MWTL is now accepting submissions of up to four pages (3 pages of text plus up to 1 page of references).

IEEE supports the publication of Chinese, Japanese, and Korean (CJK) author names in the native language alongside the English versions of the names in the author list of an article. For more information, please click here.

Call for Applicants: MWTL Editor-in-Chief

The IEEE Microwave Theory and Technology Society (MTT-S) invites applicants for the position of Editor-in-Chief (EiC) for the IEEE Microwave and Wireless Technology Letters (MWTL) for a three–year term starting on January 1, 2025.

The EiC organizes the peer review of the received manuscripts, provides constructive feedback to the authors, makes acceptance decisions, and assembles each issue of the periodical for transmission to IEEE Publications. The EiC assembles a panel of Track and Associate Editors covering different subject areas, and an editorial assistant to help carry out the editorial work. The editorial work must be compliant to the IEEE Technical Activities Board (TAB) and Publications policies. The EiC appointment is for a period of three years and is subject to the approval of the MTT Society Administrative Committee. The EiC reports to the MTT Society Adcom through its Publications Committee at three meetings each year and is expected to attend the IEEE Panel of Editors meeting that takes place once per year.

The application can be made online by filling in the form and the deadline is January 31, 2024. No late application will be considered.

For any inquiry of information, please contact the Search Committee Chair, Professor J.-C. Chiao at chiao@ieee.org.
