300MHz to 11GHz Precision
Dual RF Power Detector
The LTC
5533 is a dual channel RF power detector for RF
applications operating in the 300MHz to 11GHz range.
Two independent temperature compensated Schottky di-
ode peak detectors and buffer amplifiers are combined in
a small 4mm
×
3mm DFN package.
The RF input voltage is peak detected using on-chip
Schottky diodes. The detected voltage is buffered and
supplied to the V
OUT
pins. A power saving shutdown mode
reduces current to less than 2
μ
A/channel. The initial
output starting voltages can be precisely adjusted using
the V
OS
pins.
The LTC5533 operates with input power levels from
–32dBm to 12dBm.
