The F2480 is a 400MHz to 3000MHz RF Analog Variable 获得 Amplifier (AVGA) that can be used in receivers, transmitters, and 其他 应用s. Either the amplifier or Voltage Variable Attenuator (VVA) can be configured as the first stage in the cascade. The F2480 RF AVGA provides a 12dB typical maximum cascade 获得 (no attenuation) with a 4.3dB noise figure (amplifier as first stage) and a 36dB 获得 adjustment designed to operate with a single +5V supply. Nominally, the Zero-Distortion™ amplifier offers +41.5dBm 输出IP3 using 106mA of ICC. This device is 包裹d in a 5mm x 5mm, 32-TQFN with 50? single-ended RF input and RF 输出阻抗s for ease of integration into the signal-path lineup.
