Voltage and TTL-controlled attenuators reduce RF signal power
Pasternack has launched a new line of voltage-controlled analog attenuators and TTL programmable attenuators. These new models offer comprehensive frequency coverage from 1 MHz to 50 GHz and are designed to provide precise and reliable signal attenuation for a variety of applications. Pasternack’s new voltage-controlled analog attenuators offer a broad attenuation range of up to…
Experiments bring hope for 6G above 100 GHz
Efforts to explore and “unlock” this frequency region require an interdisciplinary approach with high-frequency RF semiconductor technology. The THz region also shows great promise for many application areas ranging from imaging to spectroscopy to sensing.
Gain blocks target 4G/5G
Guerrilla RF, Inc. announces the production release of the GRF2010 and GRF2011, two high linearity gain blocks targeting infrastructure applications such as 5G/4G base stations, automotive telematics, and cellular repeaters/DAS. These new cores extend the gain coverage for GRF’s existing portfolio of general-purpose RF/microwave gain blocks. When used in conjunction with the popular GRF2013, customers can now choose from a…
Analyzer software automates radar test
Anritsu Company introduces the Pulse Radar Measurement Function MX284059B software for its Signal Analyzer MS2840A that creates a single-instrument solution for automated pulse radar measurements to dramatically reduce cost-of-test and test time on the production line and in the field. The MS2840A, when equipped with the new software and the USB Peak Power Sensor MA24406A/18A/40A, supports tests of…
Test methods for mmWave AiP designs bring tradeoffs
Engineers have several mmWave over-the-air test methods available for evaluating phased-array antennas used in antenna-in-package designs. Each has pros and cons.
How does 5G’s O-RAN E2 interface work?
Open radio-access networks (Open RAN) disaggregate a cell tower’s baseband unit into three units. The 5G Open RAN architecture specified by 3GPP separates functions into a centralized unit (CU) and distributed unit (DU), where these functions were otherwise contained in the baseband unit, which also included the radio. These units provide network operators with the…
External GPU digitally down converts captured RF signals
Spectrum Instrumentation’s complete line of PCIe digitizer cards can now perform Digital Down Conversion (DDC) thanks to a low-cost option for $390 that uses an external GPU card for continuous “on-the-fly” processing. DDC is a powerful technique that is commonly used in a wide range of communication systems, like digital radio, radar, mobile telephony, and…
Pushbutton attenuators address cellular, wireless, satellite, and test equipment
Pasternack has just introduced a new series of push-button attenuators to address multiple applications, including test instrumentation and cellular, wireless, and satellite communications. Pasternack’s new line of continuously variable attenuators features even greater maximum power ratings of 5 watts and 10 watts, an operating frequency range of up to 18 GHz, and attenuation levels of…
