Low Noise RF Amplifier (LNA)
Broadband Low Noise RF Amplifier (LNA)
The LNAM series low noise amplifiers are designed to drive lithium niobate modulators. These amplifiers enhance the RF input signal to reach modulator’s Vp at high frequencies. They use 50 Ohm SMA connectors and operate within a frequency range of 50 kHz to 50 GHz.We provide cost-effective low-noise amplifiers with frequencies from 0.01-67GHz, a gain of 20 to 60dB, a peak of +5 to +27 dBm, and connectors from SMA of 1.85mm.

System integration
Integration and compatibility
Use these checks to connect Broadband Low Noise RF Amplifier (LNA) to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Connectors: SMA RF connectors (8.86 mm)
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Control interface
- Power Supply: No, Yes · Driver type: Dual-channel broadband low-noise RF amplifier (DLNA series)
- Match supply voltage, analog or digital command range, connector pinout and default optical state to the instrument interlock. Confirm the unpowered state explicitly — it decides what happens to the link on a power failure.
