AB - A low‐noise module comprises a low‐noise amplifier and a new type of passive balun, which consists of two λ/8 broadside‐coupled lines and a short redundant line, is presented. The on‐chip balun is not only low lossy and compact size but also provides good amplitude and phase balances at output ports over a quite wide frequency range. The method of designing the new‐type balun fabricated with CMOS IC technology is proposed. An experimental prototype operated at K‐band was designed and fabricated with a commercial 0.18‐μm CMOS technology to verify the effectiveness of the proposed design method. The measured results show the single‐to‐differential gain is about 9 dB, the amplitude imbalance of the output ports is less than 1.0 dB associated with the phase difference of 181 ± 3° over the frequency range of 20–40 GHz. The area of the prototype including the RF probe pads is about 0.73 × 1.28 mm2. © 2012 Wiley Periodicals, Inc.
