IDTF1751NBGI

RF to IF Single Downconverting Mixer GENERAL DESCRIPTION This document describes the specifications for the IDTF1751 Zero-DistortionTM Midband RF to IF Single Downconverting Mixer. This device is part of a series of mixers using lowside or highside LO injection options for all UTRA frequency bands. See the Part# Matrix for the detail of all devices in this series. The F1751 single channel device is designed to operate with a single 5V supply. It is optimized for operation in a Multi-mode, Multi-carrier BaseStation Receiver over the frequency range from 1400MHz to 2500MHz using either lowside or highside LO. IF frequencies from 50MHz to 500MHz are supported. Nominally, the device offers +43dBm Output IP3 using HS LO or +37.5dBm using LS LO with 190mA of ICC. COMPETITIVE ADVANTAGE In typical basestation receivers, the RF to IF mixer dominates the linearity performance for the entire receive system. The Zero-DistortionTM family of mixers dramatically improve the maximum signal levels (IM3 tones) that the BTS can withstand at a desired Signal to Noise Ratio (SNR.) Zero-DistortionTM technology allows realization of either benefit. In basestation transmitters, digital pre-distortion (DPD) is employed to improve the Transmitter performance. By utilizing an ultra-linear mixer in the DPD RX path, such as the IDTF1751, the ACLR and/or power consumption of the full Tx system can be improved significantly. This is because the F1751 can directly drive an ADC through an Anti-Alias filter....
