LTC5505-2ES5#TRMPBF

LTC5505-2 is a RF power detector for RF applications operating from 300MHz to 3.5GHz range. 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 VOUT pin. A power saving shutdown mode reduces supply current to less than 2µA. It is widely used in applications such as multimode mobile phone products, PCS devices, wireless data modems, wireless and cable infrastructure, RF power alarm, envelope detector etc.

• Power range is -32dBm to 12dBm
• Temperature compensated
• Buffered detector output
• Wide VCC range is 2.7V to 6V
• Low operating current is 0.5mA typical at (SHDN = HI, IVOUT = 0mA)
• VOUT slew rate is 10V/µs typical at (VRFIN = 2V step, CLOAD = 33pF, RLOAD = 2K)
• VOUT noise is 1.4mVP-P typical at (VCC = 3V, noise BW = 1.5MHz, 50 ohm RF input termination)
• Operating temperature is -40°C to 85°C
• Package style is 5-lead plastic SOT-23
