Overview

Internal Schottky Diode RF Detector with Two Input Power Ranges:

LTC5505-1, –28dBm to 18dBm
LTC5505-2, –32dBm to 12dBm

Wide Input Frequency Range: 300MHz to 3GHz (LTC5505-1); 300MHz to 3.5GHz (LTC5505-2)
Temperature Compensated
Buffered Detector Output
Wide V_CC Range of 2.7V to 6V
Low Operating Current: 0.5mA
Low Shutdown Current: <2µA
Low Profile (1mm) ThinSOT^™ Package

The LTC5505-X is an RF power detector for RF applications operating in the 300MHz to 3.5GHz range. A temperature compensated Schottky diode peak detector and buffer amplifier are combined in a small 5-pin ThinSOT package. The supply voltage range is optimized for operation from a single lithium-ion cell or 3xNiMH.

The RF input voltage is peak detected using an on-chip Schottky diode. The detected voltage is buffered and supplied to the V_OUT pin. A power saving shutdown mode reduces supply current to less than 2µA.

The LTC5505-1 operates with input power levels from –28dBm to 18dBm. The LTC5505-2 operates with input power levels from –32dBm to 12dBm.
