The company has released pre-filtered low noise amplifiers (LNAs) for GPS and other frequency bands. The GPS offering can cover L1, L2, L5, or combinations of those frequency bands. Gains available are 16 to 40 dB with noise figures typically 1.8 dB or less. These pre-filtered LNAs are designed for harsh military environments with products supplied to various missile applications.
