Analog Devices’ claims that its new AD8319 accurately measures RF (radio frequency) signals over the industry’s widest frequency range of 1 MHz to 10 GHz.

claims that its new AD 8319 accurately measures RF (radio frequency) signals over the industry’s widest frequency range of 1 MHz to 10 GHz.

A demodulating log amp, the AD8319 provides precise, temperature-stable performance over the full range of –40 degrees C to +85 degrees C, and offers accurate RF measurement of better than +/–1 dB over a dynamic range of 40 dB.

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 the company’s ADL5330. For radar applications, the device has an output response time of eight nanoseconds, enabling RF burst detection to beyond 125 MHz.

The AD8319 operates over a supply voltage range of 3 V to 5.5 V, consuming only 20 mA; power consumption is reduced to less than 1 mW when the device is disabled.
