DC1545A-A: Demo Board for LT5578 0.4GHz to 2.7GHz High Linearity Upconverting Mixer.

The LTC5584 is a direct conversion quadrature demodulator optimized for high linearity receiver applications in the 30MHz to 1.4GHz frequency range. It is also usable in the 10MHz to 30MHz and 1.4GHz to 2GHz ranges with reduced performance. It is suitable for communications receivers where an RF signal is directly converted into I and Q baseband signals with bandwidth of 530MHz or higher. The LTC5584 incorporates balanced I and Q mixers, LO buffer amplifiers and a precision, high frequency quadrature phase shifter. In addition, the LTC5584 provides four analog control voltage interface pins for IIP2 and DC offset correction, greatly simplifying system calibration.The high linearity of the LTC5584 provides excellent spurfree dynamic range for the receiver. This direct conversion demodulator can eliminate the need for intermediate frequency (IF) signal processing, as well as the corresponding requirements for image filtering and IF filtering. These I/Q outputs can interface directly to channel-select filters (LPFs) or to baseband amplifiers.Applications LTE/W-CDMA/TD-SCDMA Base Station Receivers Wideband DPD Receivers Point-To-Point Broadband Radios High Linearity Direct Conversion I/Q Receivers Image Rejection Receivers
