Description
The W7020 radio module is a short-range microwave-
frequency radio transceiver for
Bluetooth
links. It
operates in the globally available 2.4 GHz to 2.5 GHz
ISM band. The radio is based on a bipolar
complementary metal-oxide semiconductor (BiCMOS)
RF integrated circuit. The antenna filter and the RX and
TX baluns are all integrated into the radio subsystem
(see Figure 1).
As illustrated in Figure 2, the radio module requires
only an external antenna connected through a 50
characteristic impedance line and a 13 MHz crystal or
reference clock signal to enable
Bluetooth
radio
communication links. It interfaces to a baseband
controller through the serial interface bus and separate
strobe signals to create a complete
Bluetooth
hardware
solution.
