LT5572EUF
型号:
LT5572EUF
品牌:
亚德诺/凌力尔特
产品分类:
调制解调器
描述:
特点,Direct Conversion from Baseband to RF,High Output: –2.5dB Conversion Gain,High OIP3: +21.6dBm at 2GHz, Low Output Noise Floor at 20MHz Offset: ??No RF: –158.6dBm/Hz ??P OUT = 4dBm: –152.5dBm/Hz ,Low Carrier Leakage: –39.4dBm at 2GHz,High Image Rejection: –41.2dBc at 2GHz,4-Channel W-CDMA ACPR: –67.7dBc at 2.14GHz,Integrated LO Buffer and LO Quadrature Phase Generator,50Ω AC-Coupled Single-Ended LO and RF Ports,High Impedance DC Interface to Baseband Inputs with 0.5V Common Mode Voltage,16-Lead QFN 4mm × 4mm Package,典型应用,典型应用,描述,描述 The LT5572 is a direct I/Q modulator designed for high performance wireless applications, including wireless infrastructure. It allows direct modulation of an RF signal using differential baseband I and Q signals. It supports PHS, GSM, EDGE, TD-SCDMA, CDMA, CDMA2000, W-CDMA and other systems. It may also be con? gured as an image reject up-converting mixer by applying 90° phase-shifted signals to the I and Q inputs. The high impedance I/Q baseband inputs consist of voltage-to-current converters that in turn drive double-balanced mixers. The outputs of these mixers are summed and applied to an on-chip RF transformer which converts the differential mixer signals to a 50Ω single-ended output. The four balanced I and Q baseband input ports are intended for DC coupling from a source with a common mode voltage level of about 0.5V. The LO path consists of an LO buffer with single-ended input and precision quadrature generators that produce the LO drive for the mixers. The supply voltage range is 4.5V to 5.25V.
