EVALUATION BOARD

Figure 24 shows the schematic for the ADL5534 evaluation

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

components used on the board are listed in Table 6.

Transformers (T1 and T2) are provided so the ADL5534

can be configured as a balanced amplifier. Applying 5 V to

VPOS biases the amplifier corresponding to RFIN1 and

RFOUT1. Applying 5 V to VPOS1 biases the amplifier

corresponding to RFIN2 and RFOUT2. To bias both amplifiers

from a single supply, connect 5 V to VPOS or VPOS1 and

attach a jumper across W3.
