Pasternack’s new voltage-controlled analog attenuators offer a broad attenuation range of up to…
How does PAPR reduction improve power amplifier efficiency?
5G’s Orthogonal Frequency Division Multiplexing (OFDM) brings with it a major design challenge, namely an inherent wide dynamic variation between a signal’s peak and the average power. The peak-to-average power ratio (PAPR) leads to inefficient transmission performance. That’s because the OFDM waveform is created by the sum of multiple sinusoidal signals that can exhibit constructive…
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…

Open RAN networks pass the time
Network elements must meet certain frequency, phase, and time requirements to ensure proper end-to-end network operation. Synchronization architectures defined by the O-RAN alliance dictate how Open RAN equipment can meet these requirements. Open RAN continues to attract interest from service providers looking to reduce cost, improve competition, and drive technology innovation. The desire for a…
How timing propagates in a 5G network
5G’s high speeds place extreme demands on the components that maintain accurate time. Compliance with industry timing standards calls for accuracy in the face of temperature changes, shock, and vibration.
Look inside the 5G mmWave signal chain
Millimeter wave signals provide wider bandwidths and higher data rates than signals at lower frequencies. Take a look at the overall signal chain that falls between the antenna and the digital baseband. 5G new radio (5G NR) adds mmWave frequencies to cellular devices and networks. With that comes RF-to-baseband signal chains and components not needed…
