AdauraTech Helps Ensure Wireless Products Actually Work in the Real World with New RF Attenuators 

Introduction of a New 4-Channel RF Attenuator with Greater Chain-to-Chain Isolation Ensures Ultra-High Performance for Demanding Wireless Applications 

Roseville, CA – July 25, 2017 As the introduction of new wireless and IoT products accelerates, far too often the testing of these products is neglected due to cost and complexity, leading to negative performance and customer experiences. AdauraTech is the developer of high performance RF testing equipment that not only keeps up with wireless innovation, but enables both startups and incumbents alike to easily and cost-effectively test their wireless products. And today, AdauraTech introduced the next generation of its 4-channel programmable digital RF attenuators which significantly simplify wireless testing while ensuring ultra-high performance.

Like it’s predecessors, the new AdauraTech AD-USB4AR2 attenuators feature a unique design that provides 4 channels in one compact package – but this new solution also introduces innovative new engineering to deliver exceptional chain-to-chain isolation, greater than 100dB. The result is a solution that enables the testing of a much wider range of wireless applications with improved results, delivered at a better price and with greater ease of use than existing solutions on the market.

“For too long, the incredible innovation of the wireless industry has been somewhat offset by the fact that many of the new products brought to market simply don’t perform as intended in the real worl, all because they weren’t tested properly or – sometimes – at all,” said Blaise Yen, CEO of AdauraTech. “There’s a simple reason for this: RF testing has traditionally been far too expensive, and way too complex. AdauraTech’s sole mission is to remove those barriers to proper wireless testing.”

AdauraTech's multiple channel attenuators offer a compact package with a single digital interface to control multiple channels. For many applications, 63dB of total attenuation and chain-to-chain isolation is sufficient to provide excellent performance – but more advanced applications require even greater capabilities. AdauraTech’s AD-USB4AR2 provides greater than 100dB of chain-to-chain isolation with a patent pending new design, which significantly suppresses adjacent RF leakage levels. All of this is done with a design that keeps the cost down, and is paired with AdauraTech’s software for ease of use.

AdauraTech provides Quantenna with reliable, cost-effective solutions for our ever-expanding RF test requirements in both our laboratory and factory environments,” said Ray Ho, Engineering Manager at Quantenna. “In our testing, the new AD-USB4AR2 attenuators have extremely consistent performance from channel to channel, and the reliability is exceptional.”

Key Features

  • 4 Channels in one compact housing
  • 100dB of chain-to-chain isolation
  • USB/COM Interface for wide-range compatibility
  • SMA Female connectors
  • A single USB connection for power and control of all 4 channels
  • Easy to use GUI providing fixed and ramp attenuation functions

Serial Over USB Communication

…allows extremely FAST integration into existing test setups. Using any common serial console program, simply connect to the device to send it commands.

The example to the left shows a ramping function being executed on the device using the common serial program PuTTY. The command controls all FOUR of the channels simultaneously. Two of the attenuator’s channels are “Ascending” in attenuation from 0 to 5dB. At the same time, the other two channels are “Descending” from 5dB to 0dB. This command is executed with 1dB step intervals and a dwell time of 25ms.

The AD-USB4AR2 is ideal for cellular, microwave radio, IoT, MU-MIMO, and WiFi MIMO engineering development and manufacturing test. Each unit offers 4 channels of 63dB of attenuations in 0.5dB increments. Accessories include manual, GUI, programming guide, program examples on USB flash drive, along with a 5' USB Type A to B Cable. The unit is constructed in a robust compact housing with SMA female ports. Software drivers are not required for Linux machines. Simply connect to the unit like any serial device using common Linux tools such as Minicom.
