Attenuators are a form of electronic networks used to reduce the strength of an electrical signal. They are primarily used in telecommunications and radio systems to make sure that only the desired signal strength reaches a receiver. The PE43701MLI-Z attenuator is a RF/Microwave attenuator made by Peregrine Semiconductor. It is a highly integrated, active, off-chip attenuator designed to operate from DC to 13.5GHz. This attenuator is especially useful in where space is a premium as well as other applications which require low-power consumption and small size.

Application Field

The PE43701MLI-Z attenuator offers a wide range of applications in the Telecoms, military, wireless communication, and radio frequency spectrum. It can be used as an adjustable signal level blocker to protect a receiver circuit from over-voltage stress. It has excellent repeatability and minimal drift over temperature.The attenuator achieves 1dB industry level minimum attenuation range, making it ideal for use in base station and repeater applications. It is also excellent for use in mag-mounts, antennas, and other RF/Microwave products.

In the field of satellite communications, the PE43701MLI-Z can be used in the LNA or output amplifier stages to adjust gain and ensure optimal signal propagation. It is also suitable for GPS, tactical radios, and other telecommunications uses. With its wide operating frequency range and superior linearity, the PE43701MLI-Z can effectively reduce signal levels in a number of different scenarios, while retaining the desired signal strength.

Working Principle

The PE43701MLI-Z attenuator utilizes a proprietary GaAs PIN diode-based technology to provide precise attenuation control of RF/microwave signals. This technology enables quick switching times and low insertion loss with excellent repeatability and minimal drift over temperature. The attenuator is a compact, surface-mount component, ideal for high-density circuit designs. It utilizes a series-connected PIN diode structure which allows the attenuation levels to be adjusted with a single control voltage.

The device works by utilizing a single-ended voltage input to control the on/off switching of the internal PIN diodes. As the control voltage increases, the diode will respond by turning on, increasing the series attenuation in the signal path. The attenuation can be adjusted step-wise between 0dB and 8dB with a maximum attenuation of 17dB at 13.5GHz. The device also features a low-noise amplifier connected in parallel with the PIN diode, for low insertion loss. This provides excellent signal linearity, even at high input powers.

Overall, the PE43701MLI-Z attenuator is an ideal choice for various applications in the radio frequency and microwave spectrum, especially where space and power consumption are a concern. It offers excellent linearity with an adjustable attenuation range, allowing users to tailor the signal strength of their device for optimal performance.
