L1L2LNA - L1/L2 Low Noise Amplifier


GPS Sourceís L1L2LNA low-noise amplifier is a one-output, one-input in-line RF unit. It guards against intermodulation products resulting from signals out-of-band by allowing pre-selection filtering to go before the leading amplification stages.

For the L1L2LNA, there are more options than any comparable product on the market. Applications include amplifying and filtering the GPS signal produced by a passive GPS antenna as well as operations in a crowded RF signal environment demanding high gain.

The product is powered in one of three ways: GPS receiverís antenna voltage output, DC input option, or AC input voltage option. Whatever input power is used, the unit provides DC voltage output for powering an active GPS antenna. When used with a passive antenna, the input can be blocked.
