EVALUATION BOARD

Figure 6 shows the schematic for the ADL5531 evaluation

board. The board is powered by a single 5 V supply. The

components used on the board are listed in. Table 4Applying 5V

to Vpos will bias the amplifier corresponding to RFIN1 -

RFOUT2. Applying 5 V toVpos1 will bias the amplifier

corresponding to RFIN2 – RFOUT2 To bias both amplifiers

from a single supply, connect 5V to Vpos or Vpos1 and attach a

jumper across W3
