Features and Benefits
- 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: <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 VOUT 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.
