The ADL5904 is a dual-function radio frequency (RF) TruPwr™ detector that operates from dc to 6 GHz. It provides rms power measurement along with a programmable envelope threshold detection function.

The rms power measurement function has a 45 dB detection range, nominally from −30 dBm to +15 dBm. The rms power measurement function features low power consumption and an intrinsically ripple free error transfer function.

The envelope threshold detection function compares the voltage from an internal envelope detector with a user defined input voltage. When the voltage from the envelope detector exceeds the user defined threshold voltage, an internal comparator captures and latches the event to a set/reset (SR) flip flop. The response time from the RF input signal exceeding the user programmed threshold to the output latching is 12 ns. The latched event is held on the flip-flop until a reset pulse is applied.

The RF input of the ADL5904 is dc-coupled, allowing operation down to arbitrarily low ac frequencies. It operates on a 3.3 V supply and consumes 3.5 mA. A disable mode reduces this current to 100 μA when a logic low is applied to the ENBL pin.

The ADL5904 is supplied in a 3 mm × 3 mm, 16-lead LFCSP for operation over the wide temperature range of −40°C to +105°C.

Product Detail

The ADL5904-EVALZ 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.
