MRF7S38075HSR3 is type of a silicon field-effect transistor with a maximum operating frequency of 3.5GHz. It is a depletion-mode device and is also known as a Power Metal Oxide Semiconductor Field-Effect Transistor (MOSFET). It is used in radio-frequency applications like high power amplifiers and comes with an impedance of 75 Ohms.

A field effect transistor (FET) is a type of transistor that relies on the modulation of electric field density, or electric field-effect, to enable the flow of electricity from the source to the drain. According to this principle, when a voltage is applied to the control or gate terminal of the FET, it allows the current to flow from the source to the drain. This changed current will roll down the slope of the electric field, when the voltage is high enough to cause the current to become overloaded. This further helps in producing an amplified electrical output, with closely related signals.

MRF7S38075HSR3 works on the same principle, but with more efficiency. The device offers 45dB of gain, along with a maximum RF input power of 500mW, meaning it can provide an amplified output with a greater degree of linearity and improves power matching. The device also offers superior audio and RF noise figure performance and operates with exceptional linearity.

MRF7S38075HSR3 has a breakdown voltage of 30V, a drain source-off voltage of 1.4V, a drain source-on voltage of 1.2V and a power dissipation rating of 0.5W. It also has a gate threshold voltage of -3.5V. It is able to deliver high power gain up to 30dB and has an RF output of 2W. Moreover, the device has an isolation rating of 500MHz at 5V and an operating temperature range of -55°C to +150°C.

The device also offers superior thermal stability at low drain-source bias. This enables it to deliver extremely low-power consumption and reduced gate leakage current. It also has a lower capacitance, which is beneficial in high-speed applications. Additionally, the device has a wide frequency range of 28GHz to 35GHz and has a consistent gain over the entire range.
