A Dual-Band CMOS CDMA Transmitter Without External SAW Filtering

Mohammad Farazian; Bhushan Shanti Asuri; Lawrence E. Larson

A SAW-less dual-band I/Q transmitter without a driver amplifier is designed for dual-band (personal communication system (PCS)/International Mobile Telecommunications (IMT) and cellular) code division multiple access applications. The receive band noise is less than -159 dBc/Hz. It can provide up to + 5-dBm output power and meets the adjacent channel power ratio and dynamic range requirements of both PCS/IMT and cellular CDMA. The measured S 22 is better than -10 dB for both bands and it requires no external matching components. The transmitter is implemented in a 65-nm digital CMOS technology and is packaged using flip-chip technology. The transmitter signal path (RF portion) occupies 1.0 mm2.

A dual-band CMOS CDMA transmitter without SAW and Driver Amplifier

Mohammad Farazian; Bhushan Shanti Asuri; Yu Zhao; Lawrence E. Larson

A SAW-less dual-band I/Q transmitter without a Driver Amplifier (DA) is designed for dual-band (PCS/IMT, cellular) CDMA applications. The receive band noise is better than −159 dBc/Hz. It can provide up to +5 dBm output power and meets the ACPR and dynamic range requirements of both PCS/IMT and cellular CDMA. The measured S22 is better than −10 dB for both bands and it requires no external matching components. The transmitter is implemented in a 65nm digital CMOS technology, and is packaged using flip-chip technology. The transmitter signal path (RF portion) occupies 1.0 mm2.
