What does P/AR stand for?

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.

Seven New Devices Tailored Specifically for Signals with High Peak-to-Average Ratios Are Now Available HONOLULU -- Freescale Semiconductor today introduced seven LDMOS RF power transistors that deliver exceptional performance and enable WCDMA and CDMA2000 base station transmitters to exploit the full potential of the Doherty amplifier architecture.

The AD8364 is ideally suited for next-generation cellular infrastructure equipment using complex signals with constantly varying peak-to-average ratios, such as CDMA2000, W-CDMA, and TD-SCDMA.
