“…The W‐CDMA bands described in the 3GPP standard [1] are divided into the 0.8‐GHz band (bands 5, 6, and 8), the 1.4‐GHz band (band 11), the 1.7‐GHz band (bands 2, 3, 4, 9, and 10), the 2‐GHz band (band 1), and the 2.5‐GHz band (band 7). 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].…”

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.
