The AD8318 is a demodulating logarithmic amplifier, capable of accurately converting an RF input signal to a corresponding decibel-scaled output voltage. It employs the progressive compression technique over a cascaded amplifier chain, each stage of which is equipped with a detector cell. The device is used in measurement or controller mode. The AD8318 maint.
► Wide bandwidth: 1 MHz to 8 GHz
► High accuracy: ±1.0 dB over 55 dB range (f < 5.8 GHz)
► Stability over temperature: ±0.5 dB
► Low noise measurement/controller output (VOUT)
► Pulse response time: 10 ns/12 ns (fall/rise)
► Integrated temperature sensor
► Small footprint LFCSP
► Power-down feature: <1.5 mW at 5 V
► Single-supply operation: 5 V at 68 mA
► Fabricated using high speed SiGe process
APPLICATIONS
► RF transmitter PA setpoint control and level monitoring
► RSSI measurement in base stations, WLAN, WiMAX, and radars
