Linear RF amplification for complex modulated signals

The Triad RF TTRM4005QR is a quad bi-directional solid-state power amplifier operating across 4400 to 5000 MHz. Designed to accommodate signal formats ranging from CW and FM through highly modulated 64QAM and 256QAM carriers, the module uses GaN transistor technology to provide linear RF output with low distortion, while also supporting higher peak power operation at increased efficiency. Its transmit path provides 25 dB gain, with typical saturated output power of 44 dBm, while the receive path delivers 10 dB gain with a 2.5 dB noise figure.

Triad RF applies RF simulation and design techniques intended to reduce size, weight, and DC power demand while maintaining the performance required by radio-system architectures. The TTRM4005QR operates from a 12–28 VDC supply and measures 11.02 × 4.77 × 2.5 inches, providing four-channel bidirectional amplification within a compact module. Its combination of broad modulation compatibility, GaN-based RF performance, and integrated transmit and receive functionality makes it suited to radio platforms requiring efficient amplification across the 4.4–5.0 GHz band.
