ADF4351

Wideband Synthesizer with Integrated VCO

Manufactured by:

Product Details

The ADF4351 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and external reference frequency.

The ADF4351 has an integrated voltage controlled oscillator (VCO) with a fundamental output frequency ranging from 2200 MHz to 4400 MHz. In addition, divide-by-1/-2/-4/-8/-16/-32/-64 circuits allow the user to generate RF output frequencies as low as 35 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin- and software-controllable. An auxiliary RF output is also available, which can be powered down when not in use.

Control of all on-chip registers is through a simple 3-wire interface. The device operates with a power supply ranging from 3.0 V to 3.6 V and can be powered down when not in us

Applications

  • Wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT)
  • Test equipment
  • Wireless LANs, CATV equipment
  • Clock generation

Product Details

The AD-FMCOMMS6-EBZ eval board is a 400MHz to 4.4GHz receiver based on the AD9652 dual 16bit analog to digital converter, the ADL5566 High Dynamic Range RF/IF Dual Differential Amplifier and the ADL5380 quadrature demodulator.

This is an I and Q demodulation approach to direct convert (also known as a homodyne or zero IF) receiver architecture. Direct conversion radios perform just one frequency translation compared to a super-heterodyne receiver that can perform several frequency translations. One frequency translation is advantageous because it:

  • Reduces receiver complexity and the number of stages needed, increasing performance and reducing power consumption
  • Avoids image rejection issues and unwanted mixing


This topology will provide image rejection and early implementation of the differential signal environment. There is an amplification stage to maintain the full-scale input to the ACD. The local oscillator and ADC clock are on board and share the same reference signal prevent smearing. The form factor is VITA57 compliant and all of the DC power is routed from the data capture board through an FMC connector. This evaluation board demonstrates a high performance receiver signal chain aimed at military and commercial radar using “commercial off the shelf” (COTS) components. The overall circuit has a bandwidth of 220MHz with a pass band flatness of +/_ 1.0 dB. The SNR and SFDR measured at an IF of 145MHz are 64dB and 75dBc, respectively.

Product Details

The AD-FREQCVT1-EBZ is an add on board for the FMCOMMS3/4/5 boards which contain the AD9361. While the complete chip level design package can be found on the ADI product pages, information on the card, how to use it, the design package that surrounds it, and the software which can make it work, can be found on the analog wiki site.

The purpose of the AD-FREQCVT1-EBZ is frequency up or down conversion to allow the AD9361 to operate down to 1MHz.
