The ADL5506 is a complete, low cost subsystem for the measurement of RF signals in the 30 MHz to 4.5 GHz frequency range, with a typical dynamic range of 45 dB, intended for use in a wide variety of wireless terminal devices. It provides a wider dynamic range and better accuracy than is possible using discrete diode detectors. In particular, its temperature stability is excellent over −40°C to +85°C.Its high sensitivity allows measurement of low power levels, thus reducing the amount of power that needs to be coupled to the detector. It is essentially a voltage responding device, with a typical dynamic range of 45 dB.For convenience, the signal is internally ac-coupled, using a 5 pF capacitor and a broadband 50 Ω match, with an external shunt resistor of 52 Ω. This high-pass coupling, with a corner at approximately 19 MHz, determines the lowest operating frequency. Therefore, the source can be dc grounded.The ADL5506 output increases from approximately 0.14 V to a little over 1 V as the input signal level increases from 1.25 mV rms (−45 dBm) to 224 mV rms (0 dBm).

The ADM1075 typically operates froma negative voltage of -35 V to -80 V and, due to shunt regulation,has excellent voltage transient immunity. The operating range ofthe part is flexible due to the shunt regulator, and the part can bepowered directly by a 10 V rail to save shunt power dissipation(see the Powering the ADM1075 section for more details).A full-scale current limit of 25 mV or 50 mV can be selected bychoosing the appropriate model. The maximum current limit isset by the combination of the sense resistor, RSENSE, and the inputvoltage on the ISET pin, using external resistors.
