Description
Interface Schematic
RF ground connection.
RF input for the 802.11b/g TX section. Input is matched to 50Ω and DC
block is provided.
RF ground connection.
Receive port for 802.11b/g band. Internally matched to 100Ω differential.
DC block is provided internally.
Receive port for 802.11b/g band. Internally matched to 100Ω differential.
DC block is provided internally.
Switch control ports (see truth table).
Switch control ports (see truth table).
RF bidirectional port for Bluetooth. Input is matched to 50Ω and DC block
is provided internally.
Switch control ports (see truth table).
Switch control ports (see truth table).
FEM connection to filter and antenna. Port is matched to 50Ω and DC
block is provided internally.
Power detector voltage for TX section. PDET voltage varies with output
power. May need external decoupling capacitor for module stability. May
need external circuitry to bring output voltage to desired voltage.
Supply voltage for the 802.11b/g PA. Internally decoupled port with
approximately 100pF. Add an external 1uF capacitor for low frequency
decoupling.
No connection.
This is the digital enable pin for the 802.11b/g PA. This is an active high
control.
