PH2401

The PH2401 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 PH2401 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 PH2401 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.

The PH2401 is fabricated in a SiGe BiCMOS ASIC process, and is mounted in a BCC++ 48 pin package.
