HMPP-389T-BLK

RF Diode Overview

The HMPP-389T-BLK is a single shunt switch PIN diode in the MiniPak 1412 surface mount package. It features a peak inverse voltage of 100 V, a maximum series resistance of 2.5 Ω at 5 mA forward current, and a total capacitance of 0.30 pF at 5 V reverse bias. The device operates within a junction temperature range of -65°C to +150°C and has a thermal resistance of 150 °C/W. Designed for frequencies up to 6 GHz, it utilizes an epitaxial structure with a carrier lifetime of 200 ns.

• Optimized for low resistance at low current and low capacitance to support high-frequency switching applications.
• Epitaxial construction provides short carrier lifetime suitable for fast switching speeds.
• High isolation performance achieved through extremely low package parasitic inductance.

RF Diode Applications

• RF and microwave switching networks
• Shunt switches operating up to 6 GHz
• Cellular and RFID systems (930 MHz, 1.8 GHz, 2.45 GHz)
• Phase shifters and modulators

RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging configuration. The BLK suffix indicates an antistatic bag container containing 100 devices. Ensure compatibility with standard surface mount assembly processes and verify that the MiniPak 1412 pad layout matches the target PCB design.

RF Diode Selection Notes

Select this component for applications requiring wideband shunt switching with minimal signal loss. The epitaxial design offers lower resistance at low bias currents compared to bulk diodes, making it efficient for battery-operated devices. Consider the 0.30 pF capacitance and 2.5 Ω series resistance when designing matching networks for frequencies up to 6 GHz.
