Micrel's MICRF300 LNA development kits simplify the development of the MICRF300 low noise amplifier. The MICRF300 features low-power shutdown mode, which operates over the 100MHz to 1000MHz frequency band. The device is targeted for low-power, low-data rate applications at 315/433MHz, achieving a low 1.2dB noise figure with 18dB of gain, helping to improve receiver noise figure and sensitivity. It also performs well at 868/915MHz, achieving 13dB of gain and a noise figure of 1.7dB. MICRF300 requires a simple input matching network and output matching network to optimize performance for the desired frequency band.
