PRODUCTS
LNAs and receiver amplifiers for weak RF signals.
We offer low-noise amplifier solutions and custom receiver assemblies. For selection, we assess frequency range, gain and noise figure together with filtering, cable losses and dynamic range.
01 / SELECTION & INTEGRATION
Choosing the right amplifier solution
An LNA must amplify weak wanted signals while remaining sufficiently robust against interference. We match the assembly to the intended receiver and existing antenna.
- Operating frequency, gain and noise figure.
- Linearity, IP3 and compression behaviour.
- Power supply, current consumption, connections and enclosure.
02 / SELECTION & INTEGRATION
An existing assembly or a custom design
The Sevskiy LA220102-01A assembly shown here is an existing amplifier design. Please contact us to confirm current availability and the right version for your application. No approved direct DigiKey links for LNAs are currently listed in our online catalogue.
- Advice on existing amplifier solutions.
- Customisation of the frequency plan, matching, filtering and connections.
- Integration into active antennas or directly onto your PCB.
03 / SELECTION & INTEGRATION
Evaluating performance in the system
Losses before the first amplifier and possible overload of subsequent stages determine the appropriate design. We therefore assess the complete receiver path from antenna to radio chip.
- Filter placement and insertion loss.
- Coaxial cables and PCB transitions.
- Simulation and measurement of the optimised frontend.
