Applications Field: ATR4251C-PFPY can support various radio frequency applications, including LTE/5G, cellular, microwave and millimeter wave technologies, WiFi, WiMax, RFID, GPS, broadcast and wireless networking applications. It can be used as an integrated power amplifier, switch filter, low noise amplifier, or attenuator. It has a low operating voltage of < 28 V and a maximum power output of 10 W. The small size of the device makes it ideal for use in compact applications that need to save on installed space. Additionally, it has a wide temperature range of -40 to +85°C, making it suitable for use in harsh environmental conditions.

Working Principle:The ATR4251C-PFPY amplifier uses a switching technique to control the amount of power output. In this technique, two field-effect transistors (FETs) are used. One is the main FET, which controls the amount of current flowing through the amplifier. The other is the regulating FET, which is used to control the voltage. When the voltage reaches the control voltage, the regulating FET turns off, and the main FET turns on, allowing more current to flow through the amplifier. This increases the amount of power output of the amplifier. The FETs can be controlled either by using the built-in voltage regulator, or by using an external voltage controller.

ATR4251C-PFPY is a powerful and reliable RF amplifier with a wide range of applications and functions. With its small size, wide temperature range, and low power consumption, it is a great choice for a variety of RF applications. Its switching technique allows for flexible control of the amount of power output, making it an ideal choice for a wide range of applications. From basic home use to industrial applications, the ATR4251C-PFPY has you covered.
