AD8347 800MHz ~ 2. 7GHz Downconversion Wideband Quadrature Demodulator IQ RF DescriptionFirst, the product applicationThe AD8347 is a single-chip, down-conversion, broadband quadrature demodulator manufactured by Analog Devices that accepts RF inputs in the 800MHz to 2.7GHz range and downconverts the input to baseband (IF) I / Q component. The chip has the following characteristics: (1) high chip integration, simple peripheral circuits, circuit size, low power consumption. The AD 8347 integrates an RF controlled gain amplifier (AGC), a quadrature downconverter, a local oscillator driver, a DC offset zeroing circuit, and a dual differential output amplifier with adjustable DC common-mode levels. The chip even integrates a baseband level detector. The chip can provide a maximum gain of 70d B, so only a single piece of AD 8347, plus a small amount of external components, coupled with an LNA and an LO circuit, you can form a complete receiver system. The entire receiver volume can be reduced to the maximum. The AD8347 operates with a typical operating current of 64mA and consumes only 320mW at 5V. (2) Both the RF signal input port and the LO signal input port of the AD 8347 have differential input and single-ended input modes and can be driven by different L NA and VC O. Similarly, the baseband output port of the chip also has a differential Output and single-ended output in two modes, capable of driving a variety of ADC. (3) can be applied to a variety of different RF signal output circuit. AD 8347 is not only suitable for analog single-channel signal output, but also for analog dual-channel signal output. As we all know, the analog dual-channel signal output requires I / Q two output signals with excellent phase and amplitude balance, the chip can quadrature phase accuracy controlled within 1 °, I / Q imbalance control in the 0. 3d B below, well meet this requirement. (4) The AD 8347 offers a variable gain range of 70d B, with a good linear relationship between gain and control voltage over the vast majority of the operating range of the chip. Therefore, the chip can easily achieve complex wide dynamic range reception design. AD 8347 has the following four characteristics:① high integration, simple peripheral circuits, small circuit size, low power consumption; ② I / O ports are both differential and single-ended; ③ applicable to a variety of signal output RF front-end circuit; ④ with 70d B Variable gain range. Is a very easy to use AGC device.
