U FEATURES DESCRIPTIO
■
Temperature Compensated Internal Schottky
The LTC®5535 is an RF power detector for RF applications
Diode RF Detector
operating in the 600MHz to 7GHz range. A temperature ■
Wide Input Frequency Range: 600MHz to 7GHz*
compensated Schottky diode peak detector and output ■
Wide Input Power Range: –32dBm to 10dBm
amplifier are combined in a small ThinSOTTM package. The ■
External Gain Control
supply voltage range is optimized for operation from a ■
Precision VOUT Offset Control
single cell lithium-ion or three cell NiMH battery. ■
Low Starting Voltage: 200mV for Gain = 2
The RF input voltage is peak detected using an on-chip ■
Wide VCC Range of 2.7V to 5.5V
Schottky diode. The detected voltage is buffered and ■ Low Operating Current: 2mA supplied to the V ■ Available in a Low Profile (1mm) SOT-23 Package OUT pin.
U
The LTC5535 output amplifier gain is set via external
APPLICATIO S
resistors. The initial starting voltage of 200mV can be precisely adjusted using the VOS pin. ■ 802.11a, 802.11b, 802.11g, 802.15, 802.16 The LTC5535 operates with input power levels from ■ Multimode Mobile Phone Products –32dBm to 10dBm. The 12MHz baseband bandwidth is ■ Optical Data Links much higher than that of previous Schottky detector ■ Wireless Data Modems products. ■ Wireless and Cable Infrastructure ■ RF Power Alarm , LTC and LT are registered trademarks of Linear Technology Corporation. ThinSOT is a trademark of Linear Technology Corporation. ■ Envelope Detector *Higher frequency operation is achievable with reduced performance. Consult factory for more information.
