TELEWAVE's TLA760-12 763 – 824 MHz with 50 MHz bandwidth. TELEWAVE's TLA series in-line preamplifiers use surface-mount bipolar devices to amplify low level RF signals by up to 34 dB. The primary application of these preamplifiers is to improve the noise figure of a receiver system. Preamps compensate for splitter insertion loss or losses from long coaxial cable runs, and increase signal levels to spectrum analyzers or other test equipment.
