Transistors - Bipolar (BJT) - RF encompass a range of transistors specifically designed for Radio Frequency (RF) applications. The AT-30511-TR2G is one of these transistors and is particularly well suited for high-frequency applications such as base stations, RF amplifiers, cellular transceivers, high-speed data links and satellite communications.

It is mainly suitable for portable and miscellaneous small–signal and medium-power applications, offering low gain, low power consumption and low capacitance. As such, the AT-30511-TR2G is ideal for applications such as amplifiers, oscillators, frequency multipliers, wideband amplifiers, signal generators, signal modulators, switches and RF radios.

The AT-30511-TR2G is a two-stage bipolar junction transistor with a high-frequency gain of better than 8 dB at 2.4GHz. It has an operating frequency range of up to 3GHz. The package is a ceramic one, so it ensures excellent thermal conductivity and impedance stability.

The transistor is designed to operate in common base configuration and can be used in a wide variety of circuits, including capacitively coupled resonant circuits and cascode of common-collector amplifiers. It has a very stable linear operation at temperatures up to 200°C, and has a moderate power dissipation of 7.5W, making it suitable for both portable and higher-power applications.

The transistor\'s working principle depends on the flow of small current through the base-collector junction of the transistor. This small current is amplified and then used to control the current flowing from the collector to the emitter. The amount of current that is amplified is determined by the current gain of the transistor.

The AT-30511-TR2G has a transconductance of 140mS and a collector-emitter saturation voltage of 0.3V. It has a dielectric constant of 8.8, which increases its signal transmission speed. It also has a high noise figure of less than 1.5dB. Its built-in Paramp design further improves the noise figure, along with providing superior immunity to coupled noise and EMC interference.

The AT-30511-TR2G is available in different package types, including surface mount and through-hole varieties. It is rated for an operating temperature range of -55°C to 150°C. It is also RoHS and Halogen compliant, making it a better environmental choice due to its lower lead content.

In summary, the AT-30511-TR2G is ideal for high-frequency applications and is readily available in a variety of packages. Its low gain, low power consumption, low noise figure and high frequency range make it an ideal choice for both portable and high-power applications. It is a versatile transistor that can be used for a wide range of applications, ranging from amplifiers and oscillators to switches, signal generators and even RF radios.
