APPLICATION INFORMATION

RF input and output connections

Striplines, or microstrips, with an odd mode characteristic

impedance of Zo =50 Ω have to be used for the differential

RF connections on the PCB. This applies to both signal

inputs and signal outputs. Each pair of lines should have

the same length.

Grounding and power supply decoupling

The PCB ground connection has to be a large area of

copper connected to a common ground plane with an

inductance as low as possible.

To minimize low frequency switching noise in the vicinity of

the TZA3014, the power supply line should be filtered once

using a beaded capacitor circuit having a low cut-off

frequency.

The exposed die pad GNDp connection on the PCB must

be a large area of copper to aid the transfer of heat from

the IC to the PCB (see Figs 11 and 12).
