3 | 3 | The WARP radio board utilizes a dual-band direct conversion radio transceiver from Maxim, the [http://maxim-ic.com/max2829 MAX2829]. This transceiver supports both the 2.4 GHz and 5 GHz ISM bands. Although it is intended for use in 802.11a/b/g/n designs, this transceiver provides a flexible analog baseband interface. This interface allows the translation of any waveform, with a bandwidth up to 40 MHz, between baseband and RF, regardless of the waveform's adherence to an 802.11 standard. Further, when driven by a common reference clock, the phase coherency of the local oscillators in multiple MAX2829 transceivers is guaranteed. This feature is critical in MIMO applications as many algorithms require carefully controlled phase relationships and accurate measurements of phase among multiple antennas. |
