GENERAL DESCRIPTION
●The ADL5513 is a demodulating logarithmic amplifier, capable of accurately converting an RF input signal to a corresponding decibel-scaled output. It employs the progressive compression technique over a cascaded amplifier chain, each stage of which is equipped with a detector cell. The device can be used in
●either measurement or controller modes.
●FEATURES
●Wide bandwidth: 1 MHz to 4 GHz
●80 dB dynamic range (±3 dB)
●Stability over temperature: < ±0.5 dB
●Low noise measurement/controller output (VOUT)
●Pulse response time: 10 ns
●Small footprint package: 3 mm x 3 mm LFCSP
●Supply operation: 2.7 to 5.5 V at30 mA
●Fabricated using high speed SiGe process
●APPLICATIONS
●RF transmitter PA setpoint control and level monitoring
●Power monitoring in radiolink transmitters
●RSSI measurement in base stations, WLAN, WiMAX, radar
