The communication between two modems uses the time division duplex (TDD) method that a modem is either in transmit mode (activation of the transmit path) or in receive mode (activation of the receive path) in any instance. The worst case duty cycle is 0.132. The maximum user channel data rate is 1 Mbps. The modem hardware system can be divided into four units, namely, the digital and interface unit; the baseband unit; the RF unit and the power supply and battery charging unit. 2.1 Digital and Interface Unit The MCU, ML671000 from OKI, is the central controller of the whole hardware system. It is driven by a 12 MHz digital oscillator. The MCU provides an RS-232 and an USB interfaces directly. On the other hand, an Ethernet interface controller, DM9000, from DaviCom, is connected to ML671000 via the address/data buses connection to provide an RJ45 interface. Company Confidential Information Subject: Hardware Design Document Reference no.:R-001-4820-039 Title: Technical Description of Purpletooth PT-209G Wireless Modem Version no.:V2.3 Company Confidential Information Date:November 29, 2004 - 2 - 2.2 Baseband Unit The baseband unit composes of the DSSS transceiver chip set, SX043 and SX061 from AMI Semiconductor, the de-spreader, EL4450 from Elantec, and the associated filtering and matching circuitry. The baseband signal is spread by SX043 and then sent to the RF unit for up-conversion and modulation at the transmit path. In the reverse direction, the received signal at 4.6 MHz is de-spread by multiplying at the PN sequence supplied from SX043 at EL4450. The de-spread signal is demodulated at SX061 and then read by the digital control unit. 2.3 RF Unit The RF unit employs a transceiver, RF2938 from RFMD, as the core. For the transmit path, the spread data stream at 16 Mcps from SX043 of the baseband unit is modulated by the RF transceiver RF2938. The modulation scheme is either BPSK or QPSK according to the data rate selected (QPSK is only used in 1 Mbps, the maximum data rate case). The data stream is modulated to 374 MHz IF. The modulated signal is filtered and then feed back to RF2938 to further up-convert to 2.4476 GHz. The 2.4476 GHz signal is first filtered and then goes back to RF2938 where one stage power amplification is provided. The amplified signal is then further amplified by the last stage power amplifier, RF2163. Finally, the signal goes through the RF switch AS169 and the antenna port to outside. At the receiver path, the signal is first amplified by two stage LNAs, HMC287 from Hittite and RF2494 from RFMD. The signal is also down-converted to the IF at 374 MHz by RF2494. It is then filtered by a SAW filter TB374GD from Tai-SAW technology and amplified by an IF amplifier, AD8367 from Analog Devices. The IF signal is further down-converted to 4.6MHz by RF2938. This 4.6MHz signal is supplied to the baseband unit for de-spreading and demodulation. The specifications of the IF filter and amplifier are provided as follows: 2.3.1 IF SAW Filter TB374GD Item Unit Min. Type. Max. Center frequency, Fc MHz - 374 - Insertion loss, IL dB - 8.5 10 Pass bandwidth, BW3 MHz 17 24 - Amplitude ripple in Fc ± 7 MHz dB - 0.6 1 Group delay ripple in Fc ± 7 MHz ns - 40 100 Triple transit suppression dB 30 37 - Attenuation: (reference level from Min IL) Fc –100 to –33 MHz dB 45 52 - Fc –33 to –22 MHz dB 40 51 - Fc –22 to –16.5 MHz dB 30 42 - Fc +16.5 to +22 MHz dB 30 41 - Fc +22 to +43 MHz dB 35 44 - Fc +43 to +100 MHz dB 40 47 - Company Confidential Information Subject: Hardware Design Document Reference no.:R-001-4820-039 Title: Technical Description of Purpletooth PT-209G Wireless Modem Version no.:V2.3 Company Confidential Information Date:November 29, 2004 - 3 - 2.3.2 IF Amplifier AD8367 Company Confidential Information Subject: Hardware Design Document Reference no.:R-001-4820-039 Title: Technical Description of Purpletooth PT-209G Wireless Modem Version no.:V2.3 Company Confidential Information Date:November 29, 2004 - 4 - 2.4 Power Supply and Battery Charging Unit This unit provides all the necessary supply voltages to the modem system from a single 7.4V supply from a DC adaptor or a r…
