简  介:400 MHz to 6 GHz Broadband Quadrature Modulator ADL5375 FEATURES Output frequency range: 400 MHz to 6 GHz 1 dB output compression: ≥9.4 dBm from 450 MHz to 4 GHz Output return loss ≤ 14 dB from 450 MHz to 5.5 GHz Noise floor: 160 dBm/Hz @ 900 MHz Sideband suppression: <50 dBc @ 900 MHz Carrier feedthrough: <46 dBm @ 900 MHz Baseband input bias level ADL5375-05: 500 mV ADL5375-15: 1500 mV Single supply: 4.75 V to 5.25 V 24-lead LFCSP_VQ package FUNCTIONAL BLOCK DIAGRAM IBBP IBBN ADL5375 LOIP LOIN QUADRATURE PHASE SPLITTER RFOUT DSOP QBBN QBBP 07052-001 Figure 1. APPLICATIONS Cellular communication systems GSM/EDGE, CDMA2000, W-CDMA, TD-SCDMA WiMAX/broadband wireless access systems Satellite modems GENERAL DESCRIPTION The ADL5375 is a broadband quadrature modulator designed for operation from 400 MHz to 6 GHz. Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency or direct radio frequency modulation for communication systems. The ADL5375 features a broad baseband bandwidth, along with an output gain flatness that varies no more than 1 dB from 450 MHz to 3.8 GHz. These features, coupled with a broadband output return loss of ≤14 dB, make the ADL5375 ideally suited for broadband zero IF or low IF-to-RF applications, broadband digital predistortion transmitters, and multiband radio designs. The ADL5375 accepts two differential baseband inputs and a single-ended LO. It generates a single-ended 50 Ω output. The two versions offer ……
