= Wide-tuning RF Module (WDR) = [[TOC(Hardware/RFBoards/bWDR/*, depth=2)]] * RF tuning range from 300 to 7500 MHz using heterodyne downconversion and sharp IF filtering for excellent adjacent channel rejection. * Full duplex operation over entire tuning range allows any combination of uplink and downlink frequency sets. * Selectable receiver I/Q analog bandwidth of 7, 10, 15 or 20 MHz digital sampling rate of 64 MSps on I/Q with 12 bit ADC. * Receiver noise figure (NF) of 6 dB, gain control of 80 dB. * Selectable transmitter I/Q analog bandwidth of 12, 18 or 24 MHz, digital update rate of 128 MSps with 14 bit DAC. * Transmitter output of +20 dBm minimum across entire band, 32dB gain control, carrier feedthru suppression and I/Q sideband balance control. * Upto four radio channels can be configured asynchronously or locked together for phased or smart antenna applications. * Accepts external GPS frequency locking for standards based timing. * Frequency hop of less than 50usec. * Switched antenna diversity for both TX and RX channels. [wiki:Hardware/RFBoards/bWDR/aSPI SPI] block is used for control of all elements.
