APPLICATIONS INFORMATION

To generate the evaluation PCB used in the application circuit

shown in Figure 28, use proper RF circuit design techniques.

Signal lines at the RF port must have a 50 Ω impedance, and

the package ground leads and the backside ground slug must

connect directly to the ground plane. Use 300 Ω series resistors

on the BP-Chx and PD-ChAB digital control pins for glitch and

overcurrent protection.

See the ADRF5547-EVALZ user guide for additional information

on the evaluation board.
