As manufacturers move to higher frequencies, development and testing of the latest wireless systems/devices require specifically-designed test systems that can emulate a complex environment with a greater mix of device types.
Successful testing of 5G wireless technology must include over-the-air (OTA) and RF over coax testing. What is most important is to understand the advantages and disadvantages of both to determine where and when to use each test approach.
Fixed RF attenuators are versatile components that not only provide useful level control features but can be used to enhance the return loss at the input of a mismatched component/device in the signal chain. This article explains how RF fixed attenuators are used for improving the VSWR within the signal chain.
The Wi-Fi 6E standard that was established in 2021 covers a new spectrum in the so-called "6 GHz band." In response, several new products that support testing of the full range of frequencies allotted by Wi-Fi 6E have been introduced.
The value of testing with mismatch terminations is significant because high-efficiency amplifiers can be characterized by their ability to drive mismatched loads.
JFW has added a line of 50-ohm solid-state RF switches that operate 20 MHz to 8 GHz. These commercially rated models are ideal for constructing low-cost RF testbeds for automated testing. The switches are controlled with TTL control lines. The switches can hot switch up to +26 dBm with typical isolation of 55 dB at 8 GHz.
