“…W‐CDMA transceivers that can be applied to the 2‐GHz band [2–4] only were developed initially. Transceiver development then focused on supporting multiband operation, such as triple‐band operation (0.8‐GHz, 1.7‐GHz, and 2‐GHz bands) [5–9]. In addition, in Japan, a 1.4‐GHz‐band WCDMA service started in 2009; consequently, quad‐band transceivers supporting 1.4‐GHz band operation have been developed by many research institutions [10,11].…”

“…Conventionally, two approaches to the design of multiband cellular RFICs have been followed. The first approach is to introduce an LC‐type voltage‐controlled oscillator (VCO) with a wide frequency range [6–11]. Yoshida [11] devised a quad‐band W‐CDMA transceiver with a wideband VCO (operating from 2.9 to 4.0 GHz) and integer frequency dividers for each band.…”

A quad‐band (0.8, 1.7, 2, and 1.4 GHz) wideband code division multiple access (W‐CDMA) transceiver, which uses a divide‐by‐2.5 frequency divider in local parts of a direct‐conversion architecture, has been developed. Using the fractional‐2.5 frequency divider reduces the fractional bandwidth of the voltage‐controlled oscillator and avoids injection locking of the local RF synthesizer perfectly. This transceiver achieved 3% error‐vector magnitude and—46 dB ACLR, which satisfy the margin given in standard specifications. © 2012 Institute of Electrical Engineers of Japan.
