Abstract: Systems and methods are provided for a broadband, closed-loop RF transmitter for multi-band applications that employs a single RF path to service multiple bands of operation. Embodiments of the present disclosure implement a broadband impedance matching module, which avoids the need for several costly and complex narrow-band matching networks. In an embodiment, the broadband impedance matching module includes concentric, mutually-coupled inductors. By adding this broadband impedance matching functionality, delay is significantly reduced because a single path can be used to service multiple bands.

Abstract: A radio frequency receiver includes a mixer (508) for converting a radio frequency signal into an IF signal. The IF signal is then filtered and amplified by a filter (510) and automatic gain control circuit (512). The filtered and amplified IF signal is then received by an analog-to-digital converter (514) in order to convert the signal from an analog signal into a digital signal. The digital signal is then provided to a decimation filter (516) in order to convert the digital signal into a base band signal (520). The ADC (514) and decimation filter (516) both are provided with a sampling frequency signal (518) which is preferably at least four times greater than the IF signal. By using a decimation filter (516) the need for a second down conversion mixer is eliminated, thereby eliminating any associated noise, power consumption and distortion associated with using a second mixer.

Abstract: Expandable styrene-type polymer beads having a short cooling time are obtained by a method wherein styrene-type polymer beads are impregnated with a blowing agent preferably as a step separate and independent of the polymerization step or in the same suspension polymerization reactor after a substantial completion of the polymerization, in an aqueous suspension comprising styrene-type polymer beads, a blowing agent, a suspending agent, at least 0.0001% of a halide salt of a transition metal selected from the group consisting of iron, titanium, vanadium, chromium, manganese, cobalt, nickel and copper, or a mixture thereof, and at least 0.001% of glycerol mono-, di-, or tri-ester of a fatty acid having 12-30 carbon atoms or a mixture thereof, said halide being bromide, chloride or iodide, and said percentages being based on the total weight of polymer beads subjected to the impregnation, with the proviso that if said glycerol ester is a tri-ester, there must be present at least 0.
