Analog Devices Introduces Low-Drift RF Detector/Controller for Wireless Designs -AD8314 replaces discrete diode detectors to control power amplifiers and tackles difficult RF/IF measurement and control problems - Product Announcement

Cambridge Telcom Report, Feb 28, 2000

Analog Devices, Inc. Tuesday announced at Wireless Symposium/Portable by Design a new radio frequency (RF) detector/controller that enables precise, temperature-stable power amplifier control and supports all current and emerging cellular standards. The AD8314 replaces discrete diode detectors and offers wireless designers a single- package, temperature-stable IC solution.

Operating at up to a 2500 MHz operating frequency with 45 dB dynamic range, the AD8314 handles a wide signal range, enabling it to support all current and emerging cellular and PCS standards. Because the AD8314 provides precise, temperature-stable power amplifier control with 0.5 dB accuracy, designers no longer have to adjust for temperature variability during manufacturing, and design time is reduced. The AD8314 also minimizes board area due to 8-pin microSOIC packaging, which reduces required real estate by as much as 50%. With its superior functionality and performance, the AD8314 is an efficient solution for the measurement and control problems that plague RF transmitter designers.

"The AD8314 measures and controls power amplifiers with minimal temperature drift, replacing highly varying discrete diode detectors," said John Greichen, RF/IF marketing manager, Analog Processing Products, Analog Devices. "Its 0.5 dB accuracy represents a new level of performance up to 2.5 GHz, enabling an RF engineer to design a high performance transmitter. With the AD8314, Analog Devices extends its proprietary portfolio of logarithmic amplifiers for RF/IF measurement and control applications, building off the highly successful AD8313 RF Detector architecture."

Pricing and Availability

The AD8314 is priced at $3.95 in 1,000-piece quantities.
