APPLICATIONS Transmitter signal strength indication (TSSI) Wireless power amplifier input and output protection Wireless receiver input protection GENERAL DESCRIPTION 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 Rev. B 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.
