The BAR64 series is a high voltage current controlled RF resistor for RF attenuator and switches. It features a frequency range above 1MHz up to 6GHz, very low capacitance at zero volt reverse bias at frequencies above 1GHz (typ. 0.17 pF), low forward resistance (typ. 2.1 Ω @ 10 mA) and very low signal distortion
The BAR64 family consists of high‑voltage, low‑capacitance silicon PIN diodes designed for RF attenuators and switches. Various package types (SOT‑23, SOT‑323, SC‑79, etc.) are offered, each identified by a suffix such as -02L, -04W, or -07.
Key specifications include a reverse voltage of 150 V, forward current up to 100 mA, very low capacitance (as low as 0.13 pF at 1 GHz), and low forward resistance (typical 2.1 Ω at 10 mA). The datasheet also lists thermal resistance, permissible pulse loads, insertion loss and isolation performance across a wide frequency range up to 6 GHz.
