PH2402

The PH2402 Single Chip Radio Transceiver is an integrated radio transceiver optimized for use in a 2.4 GHz wireless system. Using SiGe, the design has been optimized for ultra-low power applications such as Personal Wireless Connectivity. These applications require maximum battery life, small form factor and low system cost.

The PH2402 radio is designed to meet Bluetooth Class 2 and Class 3 operation,providing ranges from 1 to 10 meters, and is fully compliant with Bluetooth Specification v1.0. Fast frequency hopping (1600 hop/s) with 79 channels available (2.402 to 2.480 GHz) and a maximum Tx & Rx bit rate of 1Mbit/s exploits the maximum channel bandwidth allowed in the ISM band.The implemented modulation techniques is Guassian Frequency Shift Keying,GFSK, with a modulation index of 0.3. The channel bandwidth is 1MHz and the frequency deviation is between 140 and 175 kHz.

The PH2402 has been designed using state-of-art circuit implementation. Features include:

• a Delta-Sigma synthesizer incorporating two point angle modulation, stabilized over the operating temperature range with calibration means for two-point angle modulation scheme.
• a transmitter power amplifier featuring programmable output levels from -10 to +2 dBm.
• a receiver architecture based on cascaded complex AGC/Filtering stages and a complex PLL demodulator.
• a fast dynamic-threshold MFSK bit slicer.
• Support for multiple crystal reference frequencies (19.2, 19.68, 19.8 MHz)
• Provides a clock output, usable by a Bluetooth Baseband Controller.
• Serial Bus Interface (SBI) along with an additional single control line constitutes the main interface to control and program the PH2402.

The PH2402 is fabricated in a SiGe BiCMOS ASIC process, and is mounted in a BCC++ 48 pin package.
