■ The LTC®5505-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. 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 VCC Range of 2.7V to 6V
Low Operating Current: 0.5mA
Low Shutdown Current: 16dBm, VCC minimum is 3V and an RF
input series resistor of 20Ω is required to limit the input current. …
