NT32012-WP: Linear - Amplifiers - Special Purpose

Linear amplifiers or linearized amplifiers refers to a type of amplifier that operates within a linear portion of the transfer characteristic of the device. The special purpose amplifier description of the NT32012-WP is one such device. The NT32012-WP is a class A, high power type linear amplifier with a wide range of applications.

The NT32012-WP is a water-cooled device, with a power connectable to 208 to 480 volts. Its operating temperature range is from -60°C to + 80°C and its storage temperature range is from -40°C to + 105°C. Its input impedance of 50 ohms is suitable for a wide range of signal sources and has a frequency range from 10 KHz to 1 GHz.

The NT32012-WP contains a three-stage single-ended amplifier sub-assembly. The first stage consists of four amplifiers in parallel, each having an output power of 471 W (at 4 dB gain). The second stage comprises two parallel amplifiers, each having a gain of 20 dB in S-parameters. Finally, the third stage is a low noise amplifier with a gain of 23 dB in S-parameters. The first stage is used to linearise the input signal, while the second and third stages provide the required gain and power levels.

In addition, the NT32012-WP contains several power control circuits. These circuits are designed to allow the user to adjust the output power level to suit their application. This can be done by adjusting the DC bias, which affects the gain and output power level. The power control circuits also include an automatic power control (APC) circuit that automatically sets the output power level depending on the input signal strength. This feature allows the user to easily set up a stable, high performance amplifier even with varying input levels.

The NT32012-WP also features a differential mode of operation. Differential operation allows the user to operate the amplifier in either push-pull or single-ended modes. This is particularly useful when amplifying signals with wide bandwidth and high harmonic content, as it helps reduce harmonic distortion and noise.

The NT32012-WP is suitable for a wide range of applications, such as base station amplifiers, radio broadcast amplifiers, high power amplifiers, and RF/microwave amplifiers. The NT32012-WP\'s ultra-high power linear amplifier configuration is suitable for high-power transmission applications in the broadcast, cable, telecommunications and military markets. Its high power, reliability and wide operating temperature range make it suitable for a wide range of applications.

Overall, the NT32012-WP is a versatile and robust amplifier with wide ranging applications in the linear amplifier space. With a power output of 471 W (at 4 dB gain), it can provide excellent linearized performance at a variety of frequencies and power levels. Its power control circuits, differential mode of operation and wide operating temperature range make it an ideal choice for many linearized amplifiers.
