The E-TA2012 3DB N4 is an attenuator kit for applications that require attenuation of radio frequency (RF) signals. It works by combining the operation of an amplifier and directional coupler to achieve signal attenuation. The amplifiers provide gain, while the directional coupler monitors the RF power and then applies varying amounts of attenuation on the output side of the amplifier. This allows for fine-tuning of the attenuation level required.

This kit is designed to provide high-performance, flexibility and low cost. It is operating between 0.1MHz and 3GHz with a linear attenuation range of 0dB to 30dB. The kit can be assembled as either a 3dB or 4dB attenuator with either an N plug or P plug connectors. Its compact size makes it ideal for applications where space is a concern.

The E-TA2012 3DB N4 attenuator is extremely easy to use. It has two input ports and one output port, with the ground port connected to the RF ground. The signal is inputted to the input port and then the signal tapped from the output port is attenuated by the variable attenuation control.

The attenuator kit is designed to provide reliable attenuation performance, with exceptional high immunity from spurious signals and good rejection of out-of-band signals. Its wide linear attenuation range and high power handling capability make it suitable for a variety of radio frequency applications such as base station downlinks, WLAN, WiMax, GPS, Bluetooth and ZigBee systems. It is also applicable for filter testing and any other requirements involving the attenuation of high frequency signals.

In addition to the main controls, the kit also features two separate thermometer controllers, which adjust the gain of the amplifiers on the input side and output side respectively for accurate power control. The thermometer controllers allow for precise control of the input and output levels, providing high-accuracy control even in low-signal applications.

The E-TA2012 3DB N4 is a versatile tool for professional RF application engineers looking for an off-the-shelf solution for their needs. It is easy to assemble and offers flexibility, performance, reliability, and low cost all in a compact package.
