ADL5904-EVALZ is an ADL5904 dual-function radio frequency (RF) TruPwr™ detector evaluation board. It is a fully populated, 4-layer, FR4-based evaluation board. A power supply of either 3V or 5V should be applied to the VPOS and GND test loops. To exercise the RMS detector portion of the circuit, the RF signal to be measured should be applied to the RFIN SMA connector. The corresponding RMS output voltage is then available on the Vrms SMA connector and on the TP1 test point. To operate the threshold detect circuitry, the RF signal that is being monitored should again be applied to the RFIN SMA connector. The DC threshold voltage that should cause the circuit to trip should be applied to the VIN_N SMA connector or to the TPVIN_N yellow test point. The internal S/R flip-flop should be reset by pressing the RST button.
