2. Radio part
Bluetooth™ Transceiver Module, model UGPZ4 has fully integrated 2.4GHz radio transceiver with Class2 power,
receiver and frequency-hopping synthesizer.
Then, UGPZ4 has also provision of Adaptive Frequency Hopping (AFH) that is used to improve the performance
of physical links in the presence of interference as well as reducing the interference caused by physical links on
other devices in the ISM band. AFH shall only be used during the connection state.

In order to facilitate power management, each section of the radio may be powered up and down separately.
Various software controllable switches have been implemented to control power to the transmitter, the frequency
synthesizer/VCO, the receiver and the LNA, if provided.

3. Base band part
Bluetooth™ Transceiver Module contains link controller, which performs all the real-time functions of the
Bluetooth™ baseband protocol layer, including data transfer and connection management. The device also
controls states of operation enables sniff, park and hold modes of operation. Real-time functions such as
frequency-hopping burst timing and clock synchronization are also implemented in this hardware. Further
processing is required to format the data into the Bluetooth™ packet format before it may be applied to the GFSK
modulator. On the receive side the controller performs error correction and de-scrambling before de-packetizing
the incoming payload and storing it in RX buffers.
The link controller hardware also implements the basic, repetitive actions of paging, inquiry, page or inquiry scans
and the general Bluetooth™ modes of park and sniff. This ensures that the processor used to implement the Link
Manager and other lower layer protocol can be kept inactive.
