Thermal Performance

The diode's 175 C maximum junction temperature (TJ) enables reliable operation in:

• Base station power amplifiers
• Military-grade RF systems
• High-density phased array antennas

MACOM's advanced packaging technology ensures thermal resistance ( JA) of just 45 C/W in the 6-WFDFN package.

Package Innovations

The 1.5 1.2mm 6-TDFN package features:

• Wettable flanks for automated optical inspection (AOI)
• Exposed pad for enhanced thermal management
• 0.5mm pitch for high-density PCB layouts

Comparative analysis shows 30% better heat dissipation than similar-sized CSP packages.

Application-Specific Performance

RF Switch Design

When used in transmit/receive switches:

• Insertion loss: <0.5dB @ 6GHz
• Isolation: >30dB @ 6GHz
• Switching speed: <50ns

Signal Processing

In mixer and detector circuits:

• Third-order intercept (OIP3): +35dBm typical
• Noise figure: <4dB
• Linearity maintained up to +20dBm input power

Design Considerations

For optimal performance:

1. Use 0402 or smaller bypass capacitors within 0.3mm of package
2. Implement thermal vias under exposed pad (minimum 4 0.2mm vias)
3. Maintain 50 impedance in all RF traces

Industry-Leading Reliability

MACOM's qualification data shows:

• MTTF >1 million hours at 125 C
• Passes 1000 cycles of -55 C to +150 C thermal shock
• Moisture sensitivity level (MSL) 1 compliant
