The basic connections for operating the ADL5534 are shown in
Figure 16. Recommended components are listed in Table 5. The
inputs and outputs should be ac-coupled with appropriately
sized capacitors (device characterization was performed with
10 nF capacitors). DC bias is provided to the amplifier via the
L1 and L2 inductors connected to the RFOUT1 and RFOUT2
pins. The recommended inductors for L1 and L2 are Coilcraft,
1008CS-471XJLC or equivalent. The bias voltage should be
decoupled using 10 nF and 1 μF capacitors. A bias voltage
of 5 V is required.

Figure 17. Connections for Operating as a Balanced Amplifier
USING BALUNS TO COMBINE BOTH AMPLIFIERS
INTO A SINGLE AMPLIFIER
The ADL5534 is ideal for use in a balanced amplifier confi-
guration. To accomplish this, flux-coupled RF transformers
with a 2:1 impedance ratio can be used for wide band
operation. Alternatively, a balun can be constructed using
lumped element components for operation over a narrow
frequency range. Figure 17 shows the necessary connections
for configuring the ADL5534 for operation as a balanced
amplifier. Figure 18 shows the performance of the ADL5534
operating in a balanced configuration.
