Specifications and Measurement of Local Oscillator Noise in Integrated Circuit Base Station Mixers - AN2021
ثبت نشده
چکیده
Residual phase noise from local oscillators (LO) can be degraded by additive noise of on-chip local oscillator drivers/buffers in integrated circuit mixers. Reciprocal mixing of strong RF signals with the LO noise degrades the receiver sensitivity. Specification and evaluation of the LO noise degradation in integrated mixers will enable a system designer to compute the loss of sensitivity in the receiver.

متن کاملSelecting High-Linearity Mixers for Wireless Base Stations
Today’s communication systems make strong demands on both receiver sensitivity and large-signal performance (dynamic range). When selecting components for a new design, therefore, it behooves the designer to focus on the performance of each one with regard to these requirements. In particular, this article deals with mixers and the basic parameters specified in their data sheets. The communicat...

In this paper, a 1.2-V RF front-end realized for the personal communications services (PCS) direct conversion receiver is presented. The RF front-end comprises a low-noise amplifier (LNA), quadrature mixers, and active RC low-pass filters with gain control. Quadrature local oscillator (LO) signals are generated on chip by a double-frequency voltage-controlled oscillator (VCO) and frequency divi...

This paper describes calibration techniques for downconversion mixers used in integrated direct-conversion receivers. A method of achieving a high even-order intermodulation rejection is presented. Using the method presented, the receiver second-order input intercept point (IIP2) can always be improved by more than 20 dB. The minimum achieved receiver IIP2 after calibration is +38 dBm. A techni...

This paper presents an integrated frequency hopped transceiver based on a subset of the cdma2000 network specifications. The circuit consists of a phase locked loop (PLL) that generates the hopping carriers, local oscillators (LOs) that generate GHz range carrier frequencies, and a series of mixers. It accepts input data in frequency shift keyed (FSK) format, and also outputs received data in F...
