RF power detector boasts wideband
coverage
The AD8319 accurately measures RF signals from 1MHz to 10GHz, and delivers an exceptional combination of low power, small packaging and fast output response time.
The AD8319, the latest addition to ADI's family of power detectors/controllers, accurately measures RF signals over the industry's widest frequency range of 1MHz to 10GHz, and delivers an exceptional combination of low power, small packaging and fast output response time Offered at the lowest price point in the AD831x family, the AD8319 allows wireless designers to trade off dynamic range for system cost

A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
The device supports all cellular standards (GSM, CDMA, W-CDMA and TD-SCDMA), broadband wireless standards (Wi-Fi, WiMAX, WiBro), and proprietary systems that operate in a variety of frequency bands.
A demodulating log amp, the AD8319 provides precise, temperature-stable performance over the full range of -40 to +85C, and offers accurate RF measurement of better than +/-1dB over a dynamic range of 40dB.
The device can also be used as a power controller when its outputs are used to adjust a PA (power amplifier) or a VGA (variable-gain amplifier), such as ADI's ADL5330.
For radar applications, the device has an output response time of 8ns, enabling RF burst detection to beyond 125MHz.
The AD8319 operates over a supply voltage range of 3 to 5.5V, consuming only 20mA; power consumption is reduced to less than 1mW when the device is disabled.
Its low power consumption and miniature package makes the device ideal for portable communications applications.
The AD8319 is sampling now, with volume production scheduled for November 2005.
It is priced at $2.99 per unit in 1000-piece quantities and is packaged in a space-saving 2 x 3mm, 8-lead LFCSP.
