The LTC5535 is an RF power detector with an RF application operating frequency range of 600MHz to 7GHz (used to identify the presence or variation of a wave, oscillation, or signal. The detector is typically used to extract the information carried). A temperature-compensated Schottky diode (diode, also known as a crystal diode, diode) is integrated in a small-profile ThinSOTTM package; it only transmits current in one direction. It is a type with a part number. A device with a terminal that has the property of flowing or not flowing according to the direction of the applied voltage) peak detector and output amplifier. The LTC5535 output amplifier gain is set by an external resistor that uses the VOS pin to accurately regulate the initial starting voltage of 200mV.
The LTC5535 operates from an input power level of -32dBm to 10dBm with a 12MHz baseband bandwidth that is much higher than previous Schottky diode detector products.
LTC5535 features: temperature compensated internal Schottky diode RF detector; wide input frequency range: 600MHz to 7GHz*; wide input power range: -32dBm to 10dBm; external gain control; precise VOUT offset control; low starting voltage: 200mV (Gain = 2); Wide VCC range: 2.7V to 5.5V; Low operating current: 2mA; Flat (1mm height) SOT-23 package.
LTC5535 applications: multi-mode mobile phone products, optical data links, wireless data modems, wireless and cable infrastructure, RF power alarms, envelope detectors, etc.
