Product Highlights
The HTH2D25P300H stands out for its advanced features, tailored for high-frequency RF systems:
High Power and Efficiency: The amplifier provides a nominal saturated output power (Psat) of 300 W. Under CW conditions, it achieves P3dB output power ranging from 309 W (2500 MHz) to 363 W (2400 MHz), with efficiency of 71.5–72.3%. At 2450 MHz, it delivers 324 W P3dB with 72.3% efficiency. Under pulsed conditions (10% duty cycle, 100 µs pulse width), P3dB ranges from 302 W (2500 MHz) to 398 W (2400 MHz), with efficiency up to 74.9% at 2450 MHz, demonstrating versatility across operating modes.
Robust Design: The GaN-on-SiC process and low thermal resistance package (0.38°C/W junction-to-case, Tj = 97°C under DC conditions) support reliable operation under high-power conditions, with a maximum junction temperature of 225°C. The amplifier withstands a 10:1 VSWR at 300 W average power (pulsed, 10% duty cycle, 100 µs pulse width, 2450 MHz) without degradation, ensuring durability under mismatched conditions.
Compact and Cost-Effective Reference Design: The evaluation board (EVB) utilizes a compact PCB (RT/Duroid 6035HTC, 30 mil thickness, er = 3.5 ± 0.05) with components like 20 pF MLCC capacitors and N-type connectors, minimizing footprint.
Enhanced ESD Protection: Internally integrated ESD design enhances reliability, with ratings of Class 1B (HBM), Class A (MM), and Class III (CDM), safeguarding the device in challenging environments.
System-Level Scalability (Multi-Device Parallel Architecture): The official evaluation board (EVB) for the HTH2D25P300H is designed with a compact, cost-optimized layout for single-device testing. However, the device supports scalable, multi-device parallel architectures,where multiple HTH2D25P300H amplifiers are combined in a multi-path parallel circuit configuration to achieve kilowatt-level RF output power. This design ensures efficient power combining and reliable performance, enabling cost-effective solutions for high-power industrial RF applications.
These features make the HTH2D25P300H an ideal choice for engineers seeking high-performance, reliable RF amplification.
