Connect ground, then the voltage detector pin, apply the three collector supplies (VC1‑VC3) at 3.3 V, apply the bias voltage (VM123) at 2.9 V, and finally apply RF input; currents will appear on the pins as listed.
The typical small‑signal gain is 31.5 dB (32 dB in some test conditions).
The device can deliver up to 27 dBm output power with 1 dB compression.
The collector supply voltage should be between 3.0 V and 3.6 V, and the bias (mirror) supply voltage is 2.9 V.
