No references found | The PowerDPD solution offers the following features: reduces the peak-to-average ratio (PAR) for single-carrier and multi-carrier signals; improves adjacent channel leakage ratio (ACLR) without the need for separate chipset or DSP; enables 45% efficiency using Axis Power Amplifiers; reduces cost for multi-channel MIMO systems; supports single and multicarrier environments; can be used in burst mode systems such as TDD-LTE and TD-SCDMA, the company said. In addition to testing for two-way level and noise, echo-return measurements and singing-return loss like their smaller cousins, the larger systems should also be expected to report peak-to-average ratio, which will determine the suitability of voice lines for data transmission. TruPwr[TM] RMS Detector Offers Industry's Best Temperature and Frequency Performance ADI's new ADL5902 TruPwr[TM] rms detector (root-to-means square detector) is designed for high-performance RF applications including power amplifier (PA) linearization/control loops, transmitter power control, transmitter signal strength indication (TSSI) and RF instrumentation that require accurate control of output power and use complex signals with highly varying peak-to-average ratios. |
