Using Calibration to Optimize Performance in Crucial Measurements
LTE Receiver Measurements
Agilent announces LTE Receiver Measurements as a software upgrade to its proven drive test platform, protecting customers’ previous investments in receiver hardware and offering multiple tests that accelerate deployment of LTE networks. Network equipment manufacturers and wireless service providers can use the software on Agilent receivers to quickly verify base station RF coverage, plot accurate coverage maps and validate planning, all of which speeds the deployment of LTE networks. The Agilent platform offers the most practical and least costly option for initial field testing, and reduces the need for a large number of far more expensive “rack-and-stack” test phones.

Spatial Channel Modeling Tool
EB announced the availability of its Spatial Channel Modeling Tool for its EB Propsim radio channel emulators for Mobile WiMAX and 3GPP LTE. The Spatial Channel Modeling Tool supports both the use of SCM and SCME channel models and is ideal for testing a range of applications including mobile devices and base stations. The Tool is based on a geometry-based stochastic modeling method for system-level emulations between multiple base stations and multiple mobile stations. Performance metrics such as throughput and delay are measured over a large number of emulation runs, called “drops”, which consist of a predefined number of radio frames. During a drop, the channel experiences fast fading according to the movement of the terminals.

VNA Frequency Extension Products
These VNA Frequency Extension products can be used with the Agilent PNA, Anritsu VNA or Rohde & Schwarz ZVA to extend the frequency range capabilities. They cover four frequency bands, from 40 up to 110 GHz, with ongoing development to extend that range to 325 GHz and beyond. The products in the range include the controller box that is used for signal routing, switching and amplification. It communicates with the analyzer providing fully automatic two-port S-parameter measurement and also provides power to the extender heads. The frequency extension head configuration can either be a transmission and or a transmission/reflection unit. It is thus possible to do either a full two-port S-parameter measurement using two T/R heads or only S21 and S11 using the T/R and T configuration.

Mini-Circuits has developed a new bias tee/diplexer (ZABT-2R15G +) that is well suited for Satellite/VSAT, LNB converter, and BUC and modems. The ZABT-2R15G+ can be used as a bias tee or diplexer that can inject 10 MHz and DC on an L-band signal. It can also be used in the reverse direction, which can strip off the DC and/or 10 MHz signal. A prime application for this model is in a satellite system where the basic architecture consists of a modem usually in the base or hub. This modem will convert IF signals to L-band (950 to 2150 MHz). The L-band will then be moved over a cable to the BUC located usually at the antenna. To minimize the length of cables and the number of cables a bias tee diplexer is used to combine the L-band signal and a separate 10 MHz signal that synchronizes the synthesizer internal to the BUC and the DC to power the BUC.

Poron Dura-shape Option
Rogers Corp. has achieved another technical first with its product line of PORON® urethanes. This unique PORON material enhancement, the Dura-ShapeTM option, is a layer of polyester sealed between two layers of PORON foam that will help fabricators produce highly accurate gaskets. This new product is the solution that fabricators have been seeking in terms of improved die cutting for high performance gaskets and seals. The “sandwiched” polyester film adds increased dimensional stability to the foam that inhibits it from changing shape during processing. This enhanced feature should allow for faster processing times. In addition to faster processing times, the increased dimensional stability and tougher tear strength of the PORON Dura-Shape option also enables more accurate die-cutting, thereby enhancing product reliability and longevity.
