- The carrier cancelling radio frequency (CCRF) is an important sub-system in the future mobile SDR (software defined Radio) terminal which employing one-step frequency down conversion before analog to digital conversion. The CCRF offers analog IF signal up to 75 MHz to an ADC sampling with 150MS/s and converting analog IF to digital IF signal. In this paper, we propose a 0.13um CMOS wideband and reconfigurable low noise amplifier, a wideband active balun, a wideband mixer, and a programmable LO which are composing a CCRF for CDMA-Cellular, WCDMA, and WiBro applications. © 2007 IEEE.
