The Logimetrics A440 is a wideband RF amplifier engineered for high-power signal applications across demanding test and operational environments. It delivers significant gain with low distortion to maintain signal integrity in critical measurement scenarios. The unit serves EMC testing, communication systems, and laboratory instrumentation where broadband performance and reliable amplification are essential.
Technical Specifications
The A440 is a wideband RF amplifier featuring microprocessor-based control architecture. Power input options align with comparable Logimetrics platforms, with typical configurations supporting either 220 VAC, 50–60 Hz, 3-Phase (up to 2.6 kW draw) or switchable 115/230 VAC single-phase operation (up to 750 VA). RF connectivity uses industry-standard connectors; comparable models employ Type N connectors for lower-frequency operation.
