Low Noise Cellular Receiver Amplifiers

Three new amplifiers suitable for low noise, high dynamic range receiver applications
Low Noise Cellular Receiver Amplifiers Low noise and high dynamic range are the keys to success for cellular base station receiver front-end amplifiers. Lower noise means slightly longer range and high dynamic range translates to less intermodulation interference from strong adjacent-channel signals. Three new low noise receiver amplifiers have...
