RF5325 Biasing Instructions:
•
802.11b/g/n Transmit
• Connect the FEM to a signal generator at the input and a spectrum analyzer at the output.
•Bias VCC to 3.3V first with VREG=0.0V
• Refer to switch operational truth table to set the control lines at the proper levels for WiFi TX.
• Turn on
VREG to 2.85V (typ.). VREG controls the current drawn by the 802.11b/g/n power amplifier and the current
should quickly rise to ~100mA±20mA for a typical part but it varies based on the output power desired. Be
extremely careful not to exceed 3.4V on the
VREG pin or the part may exceed device current limits.
•
802.11 b/g/n Receive
• To Receive WiFi set the switch control lines per the truth table below.
•
Bluetooth® Receive
•To Receive Bluetooth® set the switch control lines per the truth table below.
