Description
RF port. This port is connected with PC port by controlling 5 pin (VCTL) to
2.0V~VDD. An external capacitor is required to block the DC bias voltage
of internal circuit.
Ground terminal. Please connect this terminal with ground plane as close
as possible for excellent RF performance.
RF port. This port is connected with PC port by controlling 5 pin (VCTL) to
0V~+0.8V. An external capacitor is required to block the DC bias voltage
of internal circuit.
Ground terminal. Please connect this terminal with ground plane as close
as possible for excellent RF performance.
Control port. This terminal is set to High-Level by 2V~VDD, and Low-Level
by +0.8~0V.
Common RF port. In order to block the DC bias voltage of internal circuit,
an external capacitor is required.
Positive voltage supply terminal. The positive voltage (+2.5~+6.5V) have to
8
GND
be supplied. The bypass capacitor should be connected with GND as
close as possible for excellent RF performance.
Ground terminal. Please connect this terminal with ground plane as close
as possible for excellent RF performance.
