Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps：PB51 Application Field and Working Principle

The PB51 is a precision 6.7 GHz band power amplifier designed by LSI Industry. It is designed as a small-sized unit that enables applications to be quickly implemented without significantly impacting the cost or size of a design. As such, it is a perfect choice for many applications, from high end audio systems to military hardware. Here is an overview of the PB51\'s applications, specifications and working principles.

Applications

The PB51 power amplifier can be used for a variety of applications, including audio, video, telecommunications, control and measurement systems, security, military and more. Its dynamic range and linearity enable it to amplify and shape complex input signals, making it suitable for audio and video production and broadcasting, surveillance, navigation and navigation guidance, radar applications and more. Its wide operating temperature range from -40 to +85°C makes it suitable for use in the harshest environments.

The PB51 has been designed with both high efficiency and reliability in mind. It has an efficiency of 90%, and can operate with a low thermal drift, making it highly suitable for applications where long recordings need to be maintained with high levels of accuracy. It is also designed to deliver high output power while keeping the total power consumption low, making it suitable for a range of applications including television, radio broadcasting and cellular base stations.

Specifications

The PB51 power amplifier features a quad 12-bit D/A converter, with 8-channel simultaneous driving capability and a peak power output of up to 6.7 GHz. Its operating temperature range is from -40 to +85°C, with operating temperature range up to +90°C. It has a frequency response from DC up to 6GHz, with a gain of up to 45 dB with a flat response, very low phase noise and distortion, and a fast rise time of 5ns. It features a maximum output power of +30DBM, with output power levels adjustable VIA on-board potentiometers.

The PB51 has a wide range of integrated protection features including over temperature protection, over current protection, under voltage protection and under voltage lockout. It is further equipped with two 10mm mounting holes, two mechanical grounding points and two labeled terminal posts for connection to external test and measurement instruments.

Working Principles

The PB51 power amplifier works by amplifying high-frequency signals in the 6.7 GHz band in a linear fashion, producing a clean and accurate waveform. Incoming signals are received at the input and the amplifier is powered via a power supply voltage. The internal sensor then detects the incoming signal level, and sets the gain level accordingly. Once the gain has been set, the signal is amplified and output through the output terminals, resulting in improved signal fidelity.

The PB51 power amplifier also features a number of built-in safety measures that help to protect the unit from excessive current, voltage, temperature and signal overloads. These safety measures are designed to minimize the risk of damage to the unit and ensure safe operation.

The PB51 power amplifier is an incredibly powerful and versatile piece of kit. Its wide range of features, low price point and small size make it an ideal choice for applications where amplified power is required in a compact design. Whether used for audio, video, communications, control and measurement systems, security, military or other applications, the PB51 power amplifier has the functionality and reliability to deliver.
