Split post dielectric resonator (SPDR) operating at frequency about 10 GHz has been used for measurements of permittivity and dielectric loss tangent of thin polymer films deposited on a thin low loss polymer substrate. Uncertainty analysis and experiments have shown that it is possible to measure real permittivity and dielectric loss tangent of thin polymer films deposited on thin low loss dielectric substrates. Appropriate sensitivity of measurements can be achieved by stacking several substrates with deposited film together and thus creating multilayered dielectric structure.

The paper describes development of a technique and equipment to convert signals from TDD or FDD radio systems operating over popular ISM 2.4 GHz-band up to the less crowded, licensed 3.5GHz or 4.4GHz bands. The technique of bands conversion consists in a connection to the existing infrastructures RF up/down converter modules (transverter) with T/R switches or duplexer for TDD or FDD systems, respectively. Currently, the 3.5GHz FDD transverters cooperate in 17 locations with the IRT2000 digital radio access system used by El-net NETIA group and 4.4GHz TDD transverters work together with 802.11b WLAN AP utilized by Military Communication Institute.

The advantages of the new digital-analog principle of operation for phase shifters using ferroelectric (FE) film varactors are considered. The results of the theoretical investigation are confirmed by testing of a 1.8GHz device with a figure of merit F=120 deg/dB and a phase error < plusmn2deg in bandwidth Deltaf/f~ 5%. The response time of the phase shifter to control pulse corresponds to units of nanoseconds. On the base of analysis of properties of ferroelectric varactors the theoretical estimation of nonlinear behavior of digital-analog phase-shifter in two-tone input signal regime is executed. Expected parameters of a multilayer microstrip phased array antenna based on phase shifters with ferroelectric varactors are presented.

Radio frequency engineering and hence RF and microwave education have traditionally been based on the assignment of narrow bands of the electromagnetic spectrum. As well, signals have usually been described appropriately using discrete tones. Today digitally-modulated signal are most commonly used to transmit RF signals and the bandwidth of communication channels is broadening. The broadening is taken to the limit with proposed Ultra Wideband systems. The next generation of RF and microwave hardware engineers must have an appreciation for the complexities of signals and be grounded in wideband design.

The ever-growing demand to high-speed transmission of data has forced the designers to make faster and much more reliable circuits and systems for users. Among many of methodologies for data formats to be transmitted, the binary data is of great interest. There are various pulse code modulations (PCM) for transmission of binary data among which, non return to zero (NRZ) and return to zero (RZ) are well-known. RZ is more reliable and easier to use in comparison with NRZ but it is slower. Since there is no zero between any two bits in NRZ, its bit rate is two times more than that of RZ in the same conditions. But this reality makes the designers to consider an edge detector for NRZ data. This paper introduces a novel edge detector designed for 2.5 Gb/s clock recovery circuit. This baud rate represents the free-running frequency of phase locked loop (PLL). The advantage of this edge detector is its flexibility to encounter with frequency changes. Moreover, it doesn't dissipate constant power meaning that its dissipated power is proportional to the frequency of the received data. Therefore the jitter and extra power dissipation produced by conventional edge detectors are removed. Finally, the simulation of this edge detector for a 0.18 mum technology and its comparative results are given.

The design and development of microwave filters and networks proceeds from strong theoretical underpinnings, with readily-available theory (and software) covering such diverse areas as circuit topology, electromagnetic radiation and coupling, thermal and mechanical properties of materials, mechanical resonances and finish characteristics. However, practicality requires consideration of design and production economics, including not only labor costs, but skilled labor availability. Modern simulation tools can be applied to prediction of performance, and can include not only electrical parameters and component tolerances, but the effect of ambient operating environment and projected production delivery rates. The art of filter design requires time for mastery.
