DMF2077-000

RF Diode Overview

The DMF2077-000 is a beam-lead silicon Schottky barrier mixer diode from the Skyworks DME, DMF, and DMJ series. Designed for applications through 40 GHz, it operates in the X-band (8.2 to 12.4 GHz). The device features a bridge quad configuration with four junctions. Electrical specifications include a maximum capacitance of 0.30 pF at 0 V and 1 MHz, a typical series resistance of 8 Ω at 5 mA, a breakdown voltage of 2 V at 10 μA, and a forward voltage range of 220 to 300 mV at 1 mA. It supports low local oscillator drive levels.
