Elcom Technologies Inc. has designed a new ultra-fast, ultra-low phase noise (0.5 GHz to 40 GHz) Broadband Synthesizer. Elcom's UFS Series is based on direct-analog techniques (arithmetic operations on main and analog frequencies) combined with digital direct synthesis (DDS) for fine-step resolution. This series is suitable for radar and EW system applications where low phase noise and fast switching speeds are of primary importance. This design method allows for fast switching speeds of 200 ns and with ultra-low phase noise levels. Basic module design is used for several possible frequency ranges and step sizes that offer various customization options. These options are available in a broad range of OEM application-dependent configurations, which are tailored to specific system requirements.

AeroComm Inc.'s new transparent protocol simplifies wireless integration by allowing true plug-and-play installation of AC4424 products. This “RF-232” technology is now embedded into AC4424 industrial-temperature 2.4 GHz FHSS transceivers. RF-232 guarantees successful communication while making the process invisible to the OEM, the company says. The transceiver supports point-to-point, point-to-multipoint, and multipoint-to-multipoint configurations. It is able to broadcast data to all transceivers, or it can address packets to specific destinations using unique MAC addresses embedded into each radio. The use of 32 channels enables independent, co-located non-interfering networks. The modules will be introduced at list prices starting at $89 (1,000 unit price for 10 mW commercial unit).
