PUMD48,115 Discrete Semiconductor Products

PUMD48,115 Arrays, Pre-Biased

The PUMD48,115 Device is a multi-resistor transistor array designed specifically for use in a variety of applications, such as RF amplifiers, switching circuits and linear attenuators. It has a wide gain bandwidth, low noise, and low offset current.

The PUMD48,115 features four transistors pre-biased in a common-base configuration. The transistors are comprised of fixed resistance transistors, but with matched upper half and lower half transistors, for improved linearity and performance. The transistors are relatively small in size, all four fit into a single DIP package with an area of 48 millimeters by 115 millimeters.

The circuit is designed to provide an input signal of 1 V and an output signal of 10V with a bandwidth of 1GHz. The current gain of the circuit is 20, while the output power is 8 watts.

The operation of the circuit is based on the principle of current source. A voltage source is attached to the lower high-side resistor and a current source is applied to the upper high-side resistor. As the current flows through the transistors, the upper half will draw current and the lower half will sink current. This creates the output voltage.

The circuit also features an active current buffer that provides the flexibility and low-noise performance needed in applications such as RF amplifiers and switching circuits. The buffer amplifies the voltage signal and the current signal, so that the output signal has a higher current capability and lower noise.

The PUMD48,115 also has a variety of features that make it suitable for use in a wide range of applications. It has a low noise level, low harmonic distortion, high frequency response, and low power consumption. It can be used in applications such as audio processing, video processing, and data transmission.

The PUMD48,115 has shown to be a popular and versatile transistor array, offering low noise performance, high current capability, and excellent frequency response. It is a suitable choice for use in many different applications.
