Overview
When an amplifier has to sit inside a system rather than on a bench, such as a radar or communications transmitter, an EMC test system or a custom RF build, it is usually integrated as a module. RFlight's NTMPA modules are all-solid-state amplifiers with built-in voltage, current and temperature detection and switching control, and protection functions for reliable long-term operation.
The range falls into three groups:
- Front-end / driver modules (NTMPA-2018010, NTMPA-1804008) are compact (48 × 48mm), high-gain modules that raise a low-level signal to around 8–10W. They often drive a final-stage module.
- Final power amplifier modules (NTMPA-106050, NTMPA-6018040, NTMPA-18026540, NTMPA-26540030) deliver 30–50W with lower gain, and sit at the end of the chain, just before the antenna or load.
- -4C power amplifier modules (NTMPA-104030-4C, NTMPA-1802658-4C) are larger high-gain assemblies with CAN communication and specified harmonic suppression, for system builds that need control over a bus.
How to choose
Start with the frequency band, then the output power you need at the end of the chain. Check the gain against your available drive level: a final-stage module with ≥18dB gain needs a much stronger input than a ≥45dB driver. Allow for the supply current and heat dissipation of the final-stage modules in your mechanical design.
