Package
The LTC
®
5505-X is an RF power detector for RF applica-
tions operating in the 300MHz to 3.5GHz range. A tem-
perature compensated Schottky diode peak detector and
buffer amplifier are combined in a small 5-pin ThinSOT
package. The supply voltage range is optimized for opera-
tion 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.
