APPLICATIONS INFORMATION

BASIC CONNECTIONS

Figure 26 shows the basic connections for operating the ADL5610.

The device supports operation from 30 MHz to 6 GHz. However,

for optimal performance at lower frequency bands, the board

configuration must be adjusted. Table 6 lists the recommended

board configuration to operate the device at various frequency

bands.

Figure 26. Basic Connections

A 5 V dc bias is supplied to the amplifier through the bias inductor

connected to RFOUT (Pin 3). Decouple the bias voltage using

68 pF, 1.2 nF, and 1 µF power supply decoupling capacitors. The

typical current consumption for the ADL5610 is 92 mA.

At low frequencies, the device exhibits improved performance

with the suggested setup configuration listed in Table 6. Figure 27

and Figure 28 provide a comparison of the performance of the

device at the 30 MHz to 500 MHz band when driven with the

optimal setup configuration and the default setup configuration.
