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 current to less than 2µA. The initial offset voltage
of 120mV ±35mV can be precisely adjusted using the
VOS pin.
The LTC5531 operates with input power levels from
–32dBm to 10dBm.

■
The LTC®5531 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 ThinSOTTM package. The
supply voltage range is optimized for operation from a
single lithium-ion cell or 3xNiMH.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Specifications over the –40°C to 85°C operating temperature
range are assured by design, characterization and correlation with
statistical process controls.
Note 3: The rise time at VOUT is measured between 1.3V and 2.3V.

RFIN (Pin 1): RF Input Voltage. Referenced to VCC. A
coupling capacitor must be used to connect to the RF
signal source. The frequency range is 300MHz to 7GHz.
This pin has an internal 500Ω termination, an internal
Schottky diode detector and a peak detector capacitor.
GND (Pin 2): Ground.
SHDN (Pin 3): Shutdown Input. A logic low on the SHDN
pin places the part in shutdown mode. A logic high enables
the part. SHDN has an internal 160k pulldown resistor to
ensure that the part is in shutdown when no input is
applied. In shutdown VOUT is connected to ground via a
280Ω resistor.
VOS (Pin 4): VOUT Offset Voltage Adjustment. This pin
adjusts the starting VOUT voltage when no RF signal is
present. For VOS from 0V to 120mV, VOUT is unaffected by
VOS. For VOS > 120mV, VOUT is the sum of VOS plus the
detected RF signal.
VOUT (Pin 5): Detector Output.
VCC (Pin 6): Power Supply Voltage, 2.7V to 6V. VCC should
be bypassed appropriately with ceramic capacitors.

the input range of a variety of analog-to-digital converters.
VOUT will not change until VOS exceeds 120mV. The
voltage at VOUT for VOS ≥120mV and with no RF signal
present is:
Operation
The LTC5531 RF detector integrates several functions to
provide RF power detection over frequencies ranging from
300MHz to 7GHz. These functions include an internal frequency compensated buffer amplifier, an RF Schottky diode peak detector and level shift amplifier to convert the RF
input signal to DC and a delay circuit to avoid voltage transients at VOUT when powering up. The LTC5531 has both
shutdown and voltage offset adjustment capabilities.
VOUT = VOS
VOUT will exactly track VOS above 120mV.
RF Detector
The internal RF Schottky diode peak detector and level
shift amplifier converts the RF input signal to a low
frequency signal. The detector demonstrates excellent
efficiency and linearity over a wide range of input power.
The Schottky diode is biased at about 55µA and drives a
25pF internal peak detector capacitor.
Buffer Amplifier
The output buffer amplifier is capable of supplying typically 4mA into a load. The amplifier has a bandwidth of
2MHz and a fixed internal gain of two.
The VOS input controls the DC input voltage to the buffer
amplifier. VOS must be connected to ground if the DC
output voltage is not to be changed. The buffer is initially
trimmed to approximately 120mV with VOS connected to
ground.
Shutdown
The part is in shutdown mode when SHDN is low. The
supply current is reduced to < 2µA and VOUT is shorted to
ground via a 280Ω resistor. When SHDN is asserted high,
the part is enabled after about 8µs.
The VOS pin is used to change the initial VOUT starting
voltage. This function enables the LTC5531 output to span

Applications
The LTC5531 can be used as a self-standing signal strength
measuring receiver for a wide range of input signals from
–32dBm to 10dBm for frequencies from 300MHz to 7GHz.
Operation at higher frequencies is achievable. Consult
factory for more information.
The LTC5531 can be used as a demodulator for AM and
ASK modulated signals with data rates up to 2MHz.
Depending on specific application needs, the RSSI output
can be split between two branches, providing AC-coupled

data (or audio) output and DC-coupled RSSI output for
signal strength measurements and AGC.
The LTC5531 can be used for RF power detection and
control. Figure 1 is an example of transmitter power
control, using the LTC5531 with a capacitive tap to the
power amplifier. A 0.5pF capacitor (C1) followed by a
200Ω resistor (R1) forms a coupling circuit with about
20dB loss at 900MHz referenced to the LTC5531 RF input
pin. In the actual product implementation, component
values for the capacitive tap may be different depending on
parts placement, PCB parasitics and parameters of the
antenna.
