Resistor Networks, Arrays

The Y4485V0001AT0R is an integrated resistor network that is used in the design of high frequency applications such as RF amplifiers, signal processors, and power converters. It consists of two matched, high frequency, low-inductance resistive elements (R1 and R2) of 4.8 ohms each, and a pair of matched, low impedance Z  resistors (R3 and R4) of 0.5 ohms each. The resistors are coupled to form a bridged-tee network which is very stable, and provides a low impedance path when properly balanced.

Application Fields

The Y4485V0001AT0R is primarily used in cellular base station designs, however, its potential applications can range greatly. This integrated resistor network excels in high frequency RF signal processing applications, such as:

• Pulse and frequency generators
• RF amplifiers
• RF signal detectors
• Analog-to-digital and digital-to-analog converters
• Power converters
• RF channelizers

The Y4485V0001AT0R integrated resistor network also has application potential outside the realm of cellular base station designs. It can be utilized in consumer electronics, medical device technologies, and aerospace technologies as well. Its low profile, wide bandwidth, and high stability make it well suited for use in these applications.

Working Principle

The working principle behind the Y4485V0001AT0R is based on the concept of series and parallel resistor networks. A series network consists of two or more resistors which are connected together in a line. A parallel network is composed of two or more resistors that are connected together at each end. This type of network is used to increase or decrease the overall impedance of a circuit.

In the Y4485V0001AT0R, the two high-frequency, low-inductance resistive elements (R1 and R2) are connected in series to form a series resistor network, while the two low impedance Z  resistors (R3 and R4) are connected in parallel to form a parallel resistor network. The two networks are then combined to create a bridged-tee network which is able to provide a low impedance path for high frequency applications. Additionally, the high-frequency resistive elements are matched in order to ensure a high level of stability within the network.

Overall, the Y4485V0001AT0R is an integrated resistor network that is ideal for high frequency RF signal processing applications. Its series/parallel construction makes it stable and reliable, while its low profile and high bandwidth capabilities make it suitable for use in a variety of applications. As such, the Y4485V0001AT0R offers a great solution for designers of high frequency electronic systems.
