RF Amplifiers

The BGF802-20,127 is a type of radio frequency amplifier (RF amplifier) designed to amplify extremely low-level signals. It is commonly used in wireless applications such as wireless telemetry, test and measurement systems, satellite communications, and cellular networks. The BGF802-20,127 is also an important component in FPV (First Person View) systems used in drones and UAVs (Unmanned Aerial Vehicles).The BGF802-20,127 is a narrowband amplifer, with a specified bandwidth of up to 127MHz. It is designed to provide a maximum gain of 23 dB, with a minimum noise figure of 1.6 dB and an input/output return loss of better than 6 dB. It offers excellent linearity performance at low levels of input power, and is capable of handling a wide range of input powers from -15 dBm to +35 dBm. In operation, the BGF802-20,127 uses an input pre-stage with programs, a two stage amplifier, an output post-stage with lost filtering, and an inputRFI protection circuit. The two stages of the RF amplifier are composed of a P-channel enhancement-mode metal-oxide-semiconductor field-effect transistor (P-MOSFET). The transistor is biased into its active region, and provides the main gain stage. The output post-stage filter is designed to reduce out-of-band noise, and to reduce signal crosstalk.The input pre-stage uses an interdigital capacitor to match the input from the antenna to the amplifier. This capacitor is a key element in the overall efficiency of the amplifier. The input pre-stage of the BGF802-20,127 also provides protection for the amplifier from common mode or differential mode signal over-stress.The BGF802-20,127 is a popular choice in many different types of applications due to its excellent signal-to-noise ratio, low power consumption, small size, and excellent linearity performance. It is commonly used in wireless telemetry, satellite communications, and cellular networks, as well as in FPV systems used in drones and other UAVs. Its excellent linearity performance allows for the transmission of high quality signals, while its low power consumption helps to reduce power consumption and extend the life of the device.
