The ADL5904 is a dual function RF detector that operates from DC MHz 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. It 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 an S-R flip flop. The response time from the RF input signal exceeding the user-programmed threshold voltage is 20 ns. The latched event is held on the flip-flop until a reset pulse is applied.
The RF input of ADL5904 is dc-coupled, allowing for an arbitrarily low minimum input frequency. It operates on either a 3 V or 5 V supply and consumes 2.5 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 -55°C to +105°C.
