LTC5532 Precision 300MHz to 7GHz RF Detector with Gain and Offset Adjustment

The LTC®5532 is an RF power detector for RF applications operating in the 300MHz to 7GHz range. A temperature compensated Schottky diode peak detector and buffer amplifier are combined in a small ThinSOT™ or (2mm x 2mm) DFN package. The supply voltage range is optimized for operation from a single lithium-ion cell or 3x NiMH.

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 LTC5532 output buffer gain is set via external resistors. The initial starting voltage of 120mV ±35mV can be precisely adjusted using the VOS pin.

The LTC5532 operates with RF input power levels from –32dBm to 10dBm.

*Higher frequency operation is achievable with reduced performance. Consult factory for more information
