In the Javelin design, the Bandpass PA architecture enables the removal of the TX SAW filter.  As the RF signal from the XCVR/BB passes through the PA, the unwanted out-of-band noise produced by the transceiver is filtered out by high performance analog circuitry integrated in the CMOS 3G PA die.  Furthermore, the thermal noise produced at the PA output is greatly reduced beyond the level of a conventional GaAs PA.  The resulting signal at the output is spectrally very clean, helping to ensure the best receiver sensitivity and producing minimal interference to other radios in the system.  Figure 3 shows the wideband gain response of the Bandpass PA architecture, demonstrating the integrated TX filtering capability.  Analysis reveals that this architecture provides about 15 dB of rejection in the 3G receiver band, and about 35 dB of rejection in the GPS band.

The 8-bit CPU, running on the ~20Mhz bus clock is powerful enough to process a 6.4k sampling rate and to handle all necessary PM features. The dual array FLASH is ideal for storing the calibration values and tamper events, as well as counters without external EEPROM. The LCD module can drive up to 288 segments, which is sufficient for this type of application.

Finally, as IPsec may not always be practical for 6LoWPAN, it is highly recommended that links include strong encryption and authentication. The 2006 version of the IEEE 802.15.4 standard actually does not include a next protocol identifier”, making the detection of which protocol is being carried difficult. Although partially dealt with in the LoWPAN format using a dispatch value , it is a feature that a link should preferably have. Subnetwork design and link-layer issues are discussed in Section 2.2.

As the distance between the control board and converters is usually a short one, POF or HCS cables are often used. Fiber optic transmitters and receivers that support switching speeds from DC to 5MBd or DC to 10MBd are commonly used in this application. Table 1 provides a list of the Avago Technologies Versatile Link product family for train propulsion, and control and monitoring systems. The Versatile Link family offers a cost-effective and reliable solution to address this application. The train central computer may be located further away from the control devices, so multimode glass fiber is selected to transmit and receive optical signal over the longer distance. 

In fact, we can mix-and-match to some extent, because we could remove one pair of codes whose least-significant bit was 1 and another pair whose least-significant bit was 0 so long as these pairs are not themselves adjacent to each other.

The more intelligent manufacturing systems use sensors that enable them to observe work in progress and a control loop that allows corrective action to be taken. Thus, such manufacturing systems do not have to be as rigid because they can adapt.

The use of a single silica fiber instead of a bundle is advantageous for measuring small objects and longer distance transmission of the picked-up radiated light. The lowest measurable temperature is 500°C, because of the unavoidable optical loss in silica fibers at wavelengths longer than 2 _m. Air cooling of the sensing head is usually necessary when the temperature exceeds 1000°C.

Observe that the received power drops with the fourth power of the range, so radar systems must cope with very large dynamic ranges in the receive signal processing. The radar energy seen by the target drops proportional to the range squared. The reflected energy seen by the radar receiver further drops by a factor of the range squared. The ability to detect very small signals in the presence of large interfering signals is crucial to operate at longer ranges.
