AD8313 is a high performance logarithmic rf detector, which can convert any input signal between the 28 dBm and -115 dBm to a 50 ohm output voltage. It is specially designed for low noise receiver applications.

It is the only available logarithmic detector with an integrated logarithmic detector IC, making it an ideal choice for use in radio and radar receiver applications. This device is suitable for use in a variety of RF detection systems, including cellular, two-way radio, sonar, and automotive radar systems. It is also used to reduce noise and provide stable gain control in these systems.

The basic principles of the AD8313 detector are quite simple, and they can be broken down into five key steps. First, the incoming rf signal is converted into an alternating current (AC) signal. Next, the signal is filtered for unwanted frequencies, or “spurs.” Then a voltage-domain amplifier is used to increase the strength of the signal. Once this amplified signal reaches the detector, its instantaneous amplitude is sampled, and the detector converts this sample into a logarithm of that value. Finally, the logarithmic output of the detector is then used to establish gain levels and attenuation factors in the receiver circuit.

AD8313 devices are also typically used in test and measurement equipment, such as Network Analyzers, in order to measure the power of rf signals. In addition, these devices can be used for communication tests as well, making them ideal for use in both surveillance and research applications.

AD8313 detectors are available in 3 different packages: plastic, plastic-small, and plastic-large. The plastic-small package is the most commonly used due to its space savings. The plastic package is the least expensive option, while the plastic-large package is recommended for applications that require greater output current and higher supply voltages. All three packages offer excellent performance, with the parts operating from a 5 V supply and producing outputs from -7 dBm down to -115 dBm.

The AD8313 RF detector is a powerful tool for RF detection, and it has a wide range of applications, from signal monitoring in mobile phones to radar detection in cars. This device has a proven track record of reliable performance and is well suited to a variety of applications, making it a prime choice for RF detection. With its high accuracy and reliable performance, the AD8313 is one of the best RF detectors available.
