LTC5535ES6#PBF

LINEAR TECHNOLOGY  LTC5535ES6#PBF  芯片, 射频功率检测器, 0.6-7GHz

The is a 600MHz to 7GHz Precision RF Detector with adjustable gain and 12MHz baseband bandwidth. The supply voltage range is optimized for operation from a single cell lithium-ion or three cell NiMH 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 200mV can be precisely adjusted using the VOS pin. The LTC5535 operates with input power levels from -32 to 10dBm. The 12MHz baseband bandwidth is much higher than that of previous schottky detector products.
