DMF2454-000

RF Diode Overview

The DMF2454-000 is a beam-lead silicon Schottky barrier mixer diode from the Skyworks DME, DMF, and DMJ series. It is configured as a ring quad suitable for K-band (18.0 to 26.5 GHz) and Ka-band (26.5 to 40.0 GHz) applications. The device features low forward voltage characteristics with a maximum junction capacitance of 0.1 pF at 0 V and 1 MHz, and a typical series resistance of 18 Ω at 5 mA. It operates within an ambient temperature range of -65°C to +175°C and supports a continuous wave power dissipation of 75 mW per junction.

RF Diode Procurement Notes

Verify component authenticity by checking datasheet revision numbers against official Skyworks documentation. Confirm that the specific ordering suffix matches the required drive level and package outline drawing. Ensure handling procedures strictly follow industry-standard electrostatic discharge precautions during installation.

RF Diode Selection Notes

Select this part when designing circuits requiring low-drive performance in the K or Ka frequency bands. Evaluate local oscillator drive requirements against the specified forward voltage range to ensure optimal conversion loss and distortion characteristics. Verify that the beam-lead package dimensions align with the intended substrate layout.

RF Diode Part Context

This component belongs to the DME, DMF, and DMJ series of silicon beam-lead Schottky mixer diodes. The series covers S, C, X, Ku, K, and Ka frequency bands.
