The TC1 DESIQ Single Balun Board is an accessory board which is designed to drive the ADC1xD1x00RB in DESIQ Mode. It takes a single-ended signal (SMA input) and can drive the I+, I-, Q+ and Q- inputs to the Gig ADC Reference Board.
This board has the Mini-Circuits TC1-1-13MA+ balun on it, which rated performance is from 4.5 MHz to 3000 MHz.
Please note that this board cannot be used to drive the DESCLKIQ Mode. This is because the DESCLKIQ Mode requires I- and Q-channel inputs to be balanced more precisely than can be achieved by two separate boards attached by cables. Using this board to drive the DESCLKIQ Mode is functionally possible, but there will be a large interleaving spur, which cannot be minimized to achieve reasonable SFDR performance.
- Rated performance from 4.5 MHz to 3000 MHz
- AC-coupling performed via on-board capacitors
