AMGP-6445-TR1G

RF Amplifiers have several applications, including wireless communication, cellular communication, and continuous wave (CW) applications. The AMGP-6445-TR1G is an RF amplifier designed for wideband applications including FM, digital data, and microwave communications. It has been designed primarily as an intermediate frequency amplifier and comes in three versions: gain, pre-amplifier, and wideband amplifier.

The AMGP-6445-TR1G amplifier is based on the amplifier tree and employs the well-known cascade architecture. The amplifier tree has a main amplifier (the one connected to the power supply), an input amplifier, and an output amplifier. The main amplifier drives the input amplifier, which in turn drives the output amplifier. This type of configuration gives the amplifier an overall gain of 20 to 30dB on any frequency in the range of 10 to 500MHz.

The AMGP-6445-TR1G employs two power supplies and can be supplied with either +12V or -12V. The bipolar supply improves performance in linear operation and helps reduce noise. The amplifier also has an amplifier output stage with a built-in heat sink.

The AMGP-6445-TR1G uses a combination of both active and passive components to achieve its low noise and linearity. The amplifier uses a pair of complementary field effect transistors (FETs) for the input stage. These FETs provide a very high gain and a low noise figure, allowing for a wide bandwidth and low noise. The amplifier also uses an inductor and capacitor combination, as well as a trimmed inductor, to create the bias current and impedance matching.

The AMGP-6445-TR1G also uses a class A power compression circuit, which helps compensate for the gain-bandwidth product of the amplifier. This ensures high performance across the entire operating range. Additionally, the amplifier has a wide gain range of 0 to 100dB, which allows users to adjust the gain with a single knob.

The AMGP-6445-TR1G is designed to be a low cost RF amplifier for wideband applications. It features an excellent noise figure, linear operation, high gain at low frequencies, and an excellent dynamic range. It can be used for applications where high gain and linearity are required, such as cellular base station, and digital and microwave communication.
