EVALUATION BOARD

Figure 7 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 4

Transformers, T1 and T2 are provided so the ADL5534 maybe

configured as a balanced amplifier. Applying 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

T1, T2

T1 and T2 are 50 Ω t o100 Ω impedance transformers used to configure the ADL5534

as a balanced amplifier. T1 and T2 are used to present a 100 Ω differential impedance

to the ADL5534.
