<p>An attenuator is a device used to reducethe power level of signals passing through it, primarily electronic signals. It can be used either to reduce a signal\'s voltage or current level, or to reduce its impedance, to adapt a mismatched transformer or antenna. Attenuators are most commonly used in two-way radio systems to reduce and match the power between the base station, repeater, transmitter, and receiver of a radio.</p><p>The PXV1220S-6DBN5-T is an adjustable attenuator from the DC-6 GHz, featuring Pasternack’s wide-range, high power series design heat-sink style SMA connectors. It has an attenuation range of 16 dB, with an insertion loss of 1.2 dB and VSWR of 1.5:1. The attenuation can be adjusted from 6 to 16 dB with more accuracy than a single-step attenuator, providing greater control in a wide range of applications.</p><p><strong>Application field</strong></p><p>The PXV1220S-6DBN5-T is designed for applications in RF and microwave communication and measurement systems and equipment, including repeaters, base stations, transceivers, receivers, transmitters, and antenna tuners. It is ideal for use in a variety of industries, such as telecommunications, automotive, datacom, avionics, and military.</p><p><strong>Working Principle</strong></p><p>The PXV1220S-6DBN5-T is a wide-range, high-power attenuator that uses a series of resistors connected in a specific manner. The input signal is divided into two paths and attenuated. More specifically, it consists of four resistors: the main resistor, the control resistor, the inner resistor, and the outer resistor. The main resistor is connected in series between the input and output, and it is the primary element that determines the attenuation. The control resistor is optional and is used to adjust the amount of attenuation. The inner and outer resistors are connected in parallel between the main resistor and ground to balance the loss in each path. This design allows for a wide range of attenuation while maintaining low insertion loss.</p>
