Analog Devices AD8312 Datasheet
The AD8312 RF detector provides a complete, low‑cost solution for measuring RF signals from 50 MHz to 3.5 GHz. It offers a typical dynamic range of 45 dB and operates reliably over a temperature range of –40 °C to +85 °C, making it suitable for cellular handsets, wireless terminals, and transmitter power measurement.
The device is supplied in a 6‑ball wafer‑level chip‑scale package, consumes about 4.2 mA at 2.7 V, and features an internally ac‑coupled input with a 5 pF coupling capacitor. Its logarithmic output (VOUT) varies from about 0.02 V (no signal) to 1.8 V (full‑scale), with selectable high‑ and low‑power output ranges.
