The ADL5513 is a 1 MHz to 4 GHz, 80 dB logarithmic detector/controller. It features wide bandwidth, 80 dB dynamic range, constant dynamic range, -40oC to +85oC temperature range stability, -70 dBm sensitivity, low noise measurement/controller output (VOUT), 21 ns/20 ns pulse response time (fall/rise), single supply operation (2.7V to 5.5V @ 31 mA), power down feature (1 mW @ 5V), small footprint LFCSP and high speed SiGe process. It can be used for RF transmitter power amplifier linearization and gain/power control, power monitoring in radio link transmitters, RSSI measurement in base stations, WLAN, WiMAX, RADAR.
The ADL5513 from Analog Devices is a demodulating logarithmic amplifier that converts RF input signals to a decibel‑scaled output. It operates from 1 MHz to 4 GHz, offers up to 80 dB dynamic range, and supports both measurement and controller modes.
Key features include a single‑supply operation of 2.7 V‑5.5 V, 31 mA quiescent current, 21 ns pulse response time, and a small 16‑lead LFCSP package. The device is rated for –40 °C to +125 °C operation and includes a power‑down mode for low standby power.
