Proving Wireless Device Performance At The Network Level: Handover Test Systems JFW's Handover Test Systems are specifically designed for proving wireless device performance at the network level. These systems are based on our multi-path attenuator networks and each system comes complete with "Handover" functionality written directly into the firmware. The basic Handover Command automatically steps up the attenuation on one RF path from minimum to maximum while simultaneously stepping it down from maximum to minimum on an adjacent path.
High-Power Silicon Pin Diode SPDT Switch Datasheet The SKY12212-478LF is a high-power silicon PIN diode SPDT switch ideal for use as a high-power transmit/receive switch in a variety of telecommunication systems such as WiMAX, TD-SCDMA, or LTE base stations. This datasheet includes a detailed description of the switch, as well as information on its features and specifications.
Visual System Simulator (VSS) Software Visual System Simulator (VSS) is complete and comprehensive software for the design of today's complex communications systems. VSS technology provides engineers with the ability to design the right system architecture as well as formulate suitable specifications for each of the underlying components in the communications designs. Like AWR's flagship Microwave Office software, VSS is also built upon the AWR unique unified data model, seamlessly providing for system and circuit level co-simulation.
Absorptive High Isolation SPDT Switch The RFSW6124 is an Absorptive High Isolation SPDT Switch for high-performance communications systems (test equipment, wireless backhaul, high-performance communications systems, cellular, 3G, LTE infrastructure, etc.). This datasheet includes a detailed description of the switch, as well as information on its specifications, features, maximum ratings, nominal operating parameters, and more.
4-Way Power Dividers And Combiners Like all MCLI power dividers and combiners, the 4-Way series features stripline construction, low insertion loss, excellent amplitude balance, and low VSWR. This series is broken down into two main categories by connector type; SMA and N. (Other connector options are available by request)
Product Brochure: FSV Signal Analyzer Rohde & Schwarz is the first T&M equipment supplier to offer a test solution for 3GPP LTE uplink with MIMO technology. The current release of the R&S FS-K103PC software option for the R&S FSV, R&S FSQ, and R&S FSW signal analyzers allows chipset manufacturers to develop the components for tomorrow's user equipment.
Power Envelope Tracking For Mobile Power Amplifiers By National Instruments Corporation
Have you heard the story about the guy who had to recharge his 4G phone twice a day? Unfortunately, he was not happy with his phone. This story has been happening as the demand for high-speed data increases and battery capacity has not matched advances with communications technology. It’s not the battery at fault, but the technology needed to power the amplifier on the phone.
Now you can finally purchase the amplifier products you need to fulfill your wideband EMC and wireless applications in one amplifier. AR’s new amplifiers offer 15- to 50-watt Class A linear power versions over an instantaneous BW from 1 to 6 GHz with very low harmonic distortion for your demanding requirements.
This diplexer has an RX frequency range of 15.12 to 15.35 GHz, and a TX range of 14.7 to 14.93 GHz. Additional specifications include 230 MHz -1dB BW, <1.0 dB I.L, >50 dB isolation, >20 dB return loss, <5ns group delay ripple, an SMA-female connection, and 50Ω impedance.
Distributed antenna systems allow cellular phone use and the use of wireless data terminal connections within buildings not typically covered by wireless signals. This download provides additional information on where distributed antenna systems are common.
Wireless InSite is a suite of ray-tracing models and 2D field solvers for the analysis of site-specific radio propagation and wireless communication systems available through a common user interface. The software provides efficient and accurate predictions of propagation and communication channel characteristics in complex urban, indoor, rural, and mixed path environments.
Dow-Key Microwave’s versatile platform offers a kit-controller package that allows the end user to build and program a fully integrated switching solution at a minimum cost. The kit provides hardware, such as a 3x7-inch PCB board (with embedded software and switch patch panel) and dc-cables, for controlling and integrating Dow-Key RF switches.
