2  General description 

 

The FMC30RF is an FMC Daughter Card which is fully compliant with the VITA 57.1-2010 
standard. The FMC30RF offers in a small footprint a low power and fully featured Rx/Tx signal 
path for the development and deployment of advanced RF solutions. With a frequency range 
coverage from 400MHz to 3.0GHz (two ranges) and up to 60MHz bandwidth the FMC30RF 
provides flexibility and reconfigurability to a host of applications.  

Based on Texas Instruments RF technology the FMC30RF comprises of a dual DAC Tx IQ 
modulator, a dual ADC Rx IQ demodulator with PGA and LNA front-end and on-board clocking 
with integrated PLL/VCO. The FMC30RF allows flexible control on sampling frequency through 
serial communication busses. Furthermore the card is equipped with power supply and 
temperature monitoring and offers several power-down modes to switch off unused functions.

3  Installation 

 

3.1  Requirements and handling instructions 

  The FMC30RF daughter card must be installed on a carrier card compliant to the FMC 

standard. 

  The FMC carrier card must support the low-pin count connector (LPC 160-pins). High 

pin count is permitted. 

  The FMC carrier card must support VADJ/VIO_B voltage b1.65V and +5.5V. 

  Do not flex the card and prevent electrostatic discharges by observing ESD precautions 

when handling the card.
