.. LTC5535 Precision 600MHz to 7GHz, RF Detector with Adjustable Gain and 12MHz Baseband Bandwidth Features - - - - - - - - - DESCRIPTIO Temperature pensated Internal Schottky Diode RF Detector Wide Input Frequency Range: 600MHz to 7GHz- Wide Input Power Range: - 32d Bm to 10d Bm External Gain Control Precision VOUT Offset Control Low Starting Voltage: 200m V for Gain = 2 Wide VCC Range of 2.7V to 5.5V Low Operating Current: 2m A Available in a Low Profile (1mm) SOT-23 Package The LTC®5535 is an RF power detector for RF applications operating in the 600MHz to 7GHz range. A temperature pensated Schottky diode peak detector and output amplifier are bined in a small Thin SOTTM package. The supply voltage range is optimized for operation from a single cell lithium-ion or three cell Ni MH battery. The RF input voltage is peak detected using an on-chip Schottky diode. The detected voltage is buffered and supplied to the VOUT pin. The LTC5535 output amplifier gain is set via external resistors. The initial starting voltage of 200m V can be precisely adjusted using the VOS pin. The LTC5535 operates with input power levels from - 32d Bm to 10d Bm. The 12MHz baseband bandwidth is much higher than that of previous Schottky detector products. , LTC and LT are registered trademarks of Linear Technology Corporation.
