Attenuators are extensively used to reduce whatever signal they are given. They are components of an electrical circuit that maintains a constant power flow through the circuit. The PXV1220S-1DBN6-T is an attenuator specifically designed for use in cellular telephone communication. It is designed to reduce the transmission power of the cellular phone, preventing it from radiating too much power out of the antenna.

The PXV1220S-1DBN6-T is a surface mount terminal resistor array that has 12 total elements, each of which is 20 ohms. The resistor array design of the attenuator allows it to maintain a uniform resistance over a wide range of frequencies. It can handle signals up to a frequency that is 10 times higher than the rated frequency of the part number. The high power handling capability of the part make it suitable for both cellular phone and Wi-Fi applications.

The PXV1220S-1DBN6-T can be used for a variety of different applications, including radio frequency interference (RFI) suppression, voltage divider networks, broad-band matching networks, precision networks, isolation paths, and amplitude reflection scenarios. In addition, the part is suitable for both high-frequency and low-frequency use.

The part’s working principle is based on the concept of signal attenuation. When a signal passes through an element with a resistance, some of its energy is converted into heat. This heat represents the signal that has been attenuated, or weakened. It is this attenuation that enables the PXV1220S-1DBN6-T to reduce the transmission power of the cellular telephone.

The part is constructed of a pre-tinned resistor array and a PTFE substrate. The pre-tinned element ensures reliable performance over an extended temperature range. The parts are also rated for up to 0.1% temperature coefficients and an excellent insulation resistance. This ensures that the part maintains a consistent resistance over varying temperatures.

The PXV1220S-1DBN6-T is designed to reduce transmission power by up to 10dB. This provides a significant reduction in the amount of radiated power of the transmitter antenna, ensuring that the performance of the cellular phone is better managed. As a consequence, the range of the mobile device is also improved.

The PXV1220S-1DBN6-T is a versatile attenuator that is suitable for a variety of different applications. It is designed to reduce transmission power in cellular telephone applications and can handle a wide range of frequencies and a 0.1% temperature coefficient. The pre-tinned elements and PTFE substrate ensure reliable performance and an excellent insulation resistance, making the part an ideal choice for signal attenuation applications.
