An integrated low phase noise, fractional-N phase-locked loop (PLL) with a voltage controlled oscillator (VCO) and internal 2× multiplier generate the necessary on-chip local oscillator (LO) signal for the I/Q mixer, eliminating the need for external frequency synthesis. The VCO uses an internal autocalibration routine that allows the PLL to select the necessary settings and locks in approximately 100 µs. The single-ended reference input to the PLL operates up to 500 MHz and features internal reference dividers and a multiplier for added flexibility. Additionally, the phase frequency detector (PFD) parison frequency can be up to 250 MHz for integer mode and 160 MHz for fraction-N mode. The upconverter consists of an I/Q mixer that can operate in either I/Q mode with 500 MHz of bandwidth or in IF mode up to 3 GHz of bandwidth, which allows various radio architectures and backward patibility with legacy systems. Immediately following the I/Q mixer are stages of gain and variable attenuation. The configuration can achieve a minimum 1 d B pression point (P1d B) pression point of 19 d Bm, eliminating the...
