Adapting to a multi-band future
Mobile data services are experiencing a period of exponential growth, driven by enthusiastic adoption of smartphones and tablets in the consumer market, and expansion of applications for mobile usage, such as social networking, mobile video and video calling. Some estimates anticipate that 1.3 exabytes of data traffic will pass through the network in 2012 (‘exa’ denotes a multiplier of 1018, equivalent to 1million terabytes), with no ...
First Open-Ended RF Sleeve for Frequencies in UHF to Microwave
The Venti RF suppression sleeve is a patent-pending EMI/RFI solution that replaces the need for higher costing 1/4 wave chokes, stubs and ferrite cores. The Venti sleeve is effective at 2.4 and 5 GHz and all other frequencies above 1 GHz, opening up a whole new world for product designers and engineers that was not previously available. A small form, low labor replacement for current EMI/RFI alternatives available today, the Venti sleeve is perfe...
Industry’s First Half Watt RF Driver Amplifier with Dynamically Adjustable Bias and Extended Temperature Range
To meet the needs of today’s radio and RF communication equipment designers, Analog Devices, Inc. (ADI) today introduced the ADL5324 half-Watt RF driver amplifier. When compared to other RF driver amplifiers, the ADL5324 offers superior power efficiency and temperature tolerance. The ADL5324 operates over a wide temperature range (-40°C to +105°C), and can be biased to operate on less power.
