Analog Level Detectors 10 to 1000 MHz Technical Data UTD-1000/1001 Features Description Pin Configuration • –120 mV Output for –10 dBm Pin The UTD-1000 has an input impedance of 50 ohms. The UTD-1001 has an input impedance of greater than 300 ohms. In all other respects the detectors are similar. The level detector consists of an amplifier stage that drives a Schottky-barrier detector diode. Matched back-to-back silicon diodes which are closely thermally-coupled to the detector provide a DC tracking reference. TO-8F • ±1.0 dB Flatness • 50- or 300-Ohm Impedance Applications • Specifically Designed for System Built-in Test • RF/IF Monitor • Level Control GROUND RF IN VIDEO V+ REFERENCE • UTD-1001 Can Be Used Without a Coupler in Many Cases Schematic Maximum Ratings + Parameter V RFIN R 1000 pF –ID* Detector +ID* Reference R * Requires external bias resistors see “Application Note”, Section 7.
