APPLICATIONS INFORMATION

BIASING PROCEDURES

The ADL8150 is a self biased GaAs, MMIC, HBT, low phase

noise amplifier. Figure 41 shows the typical application circuit.

The choice of L1 and C4 are critical to obtain the performance

specified in this data sheet. L1 is a Coilcraft 0402DF-560XJR,

56 nH inductor. C4 is an American Technical Ceramics,

531Z104KTR16T, 0.1 μF capacitor.

Power the ADL8150 from a well regulated, ultra low noise

power source. The LT3045EDD#PBF ultra low noise, ultrahigh

power supply ripple rejection (PSRR) linear regulator is

recommended.

All of these components are included in the ADL8150

evaluation board circuit. For more details, see the ADL8150-

EVALZ user guide.

Adhere to the following bias sequence during power-up:

3. Apply the RF input signal.

Adhere to the following bias sequence during power-down:

1. Turn off the RF input signal.
