Introduction Bluetooth Headset ABH-204 can be carried as a wireless headset product based on Bluetooth technology. What is Bluetooth Technology? Bluetooth Technology allows the users to communicate data in the wireless network, which is the wireless network technology can be used in the short-range distance. It is designed to communicate data/voice within short-range distance of 10m to 100m. Bluetooth Technology operates in 2.4GHz ISM(Industrial Scientific Medical) of RF bandwidth, which can be used in most countries without any government regulations. Low cost, low power consumption and Robust data communication are main feature of Bluetooth Technology and Bluetooth allows Home appliance, Handheld PC/PDA, LAN PSTN, Mobile Phone to connect to wireless network, such as internet service. 2. What is in the package ? Our ABH-204 Bluetooth headset package comes equipped with a headset and charging adaptor.

Bluetooth Wireless Headset 3. Operation Description 1) General Description It supports Class2 and Class3 radio transmission without the need for an external Power amplifier. Fully integrated synthesizer without external VCO varacter diode, resonator or loop filter. It has designed for use in voice application such as hands-free kits. It has designed with low power consumption and most of can be controlled by microprocessor. 2) Radio Architecture (1) Transmitter Architecture -The Transmitter uses a conventional IQ modulator, as Figure 2.1 Shows. The Baseband Bluetooth signal is generated digitally and modulated in accordance with the Gaussian Frequency Shift Keying(GFSK) modulation scheme employed in Bluetooth. An additional frequency offset of to 1MHz can be added to the digital baseband signal. -The baseband signal is up-converted in the in-phase and quadrature (IQ) modulator to 2.4GHz. An RF amplifier then boosts the signal level and drivers differential TX_A and TX_B. -A conventional PLL synthesizer provides the local oscillator drive to the IQ modulator. The synthesizer produces signals at around 1.2GHz, which are then doubled to 2.4GHz. The 2.4GHz signal passes through a 90 phase splitter to provide the IQ driver to the modulator. The loop filter components for the synthesizer are internal to the chip.

The RF switch enables the use of inputs from either the differential or signal-ended receive ports. The differential ports are the same TX_A and TX_B ports utilized by the transmitter. Single-ended inputs used the RF_IN port. -Both differential and single-ended inputs are amplified by a low noise amplifier (LNA) and Bluetooth Wireless Headset passed to an IQ mixer where the signal is then down-converted to a first intermediate frequency (IF) of 1.5MHz. This signal is amplified and filtered before undergoing a second quadrature mix to 2.5MHz. The 2.5MHz signal is further amplified and filtered. The signal is limited, sampled and then digitally demodulated. The 2.5MHz IF block also provides received signal strength indication(RSSI).
