Precision RF Power Detector
with Gain and Offset Adjustment
August 2003
The LTC
5532 is an RF power detector for RF applications
operating in the 300MHz to 7GHz range. A temperature
compensated Schottky diode peak detector and buffer
amplifier are combined in a small ThinSOT
TM
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 V
OUT
pin.
The LTC5532 output buffer gain is set via external resis-
tors. The initial offset voltage of 120mV
±
35mV can be
precisely adjusted using the V
OS
pin.
The LTC5532 operates with input power levels from
–32dBm to 8dBm.
