■
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 ThinSOTTM package. The
supply voltage range is optimized for operation from a
single lithium-ion cell or 3xNiMH.
The LTC5532 output buffer gain is set via external resistors. The initial offset voltage of 120mV ±35mV can be
precisely adjusted using the VOS pin.

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.
Note 4: Bandwidth is calculated based on the 10% to 90% rise time
equation: BW = 0.35/rise time.
Note 5: RF performance is tested at 1800MHz
Note 6: Guaranteed by design.

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.
VOS (Pin 3): VOUT Offset Voltage Adjustment. From 0V to
120mV, VOUT does not change. Above 120mV, VOUT will
track VOS.
VM (Pin 4): Negative Input to Buffer Amplifier.
VOUT (Pin 5): Detector Output.
GND (Pin 2): Ground.
VCC (Pin 6): Power Supply Voltage, 2.7V to 6V. VCC should
be bypassed appropriately with ceramic capacitors.

reference voltage. When the internal detector output voltage (which is connected to the positive input of the buffer
amplifier) exceeds the external voltage on VM, VOUT will
switch high.
Operation
The LTC5532 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 a level shift amplifier to convert the
RF input signal to DC. The LTC5532 has both gain setting
and voltage offset adjustment capabilities.
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 120mV (Gain = 2x) with VOS connected to
ground.
Buffer Amplifier
The VOS pin is used to change the initial VOUT starting
voltage. This function, in combination with gain adjustment enables the LTC5532 output to span the input range
of a variety of analog-to-digital converters. VOUT will not
change until VOS exceeds 120mV. The starting voltage at
VOUT for VOS >120mV is:
The output buffer amplifier is capable of supplying typically 4mA into a load. The negative terminal VM is brought
out to a pin for gain selection. External resistors connected
between VOUT and VM (RA) and VM to ground (RB) will set
the gain of this amplifier.
Gain = 1 + RA/RB
VOUT = 0.5 • VOS • Gain
The amplifier is unity gain stable; however a minimum
gain of two is recommended to improve low output
voltage accuracy. The amplifier has a bandwidth of 2MHz
with a gain of 2. For increased gain applications, the
bandwidth is reduced according to the formula:
where gain is the output buffer gain. For a buffer gain of 2x,
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.
Bandwidth = 4MHz/(Gain) = 4MHz • RB/(RA + RB)
A capacitor can be placed across the feedback resistor RA
to shape the frequency response. In addition, the amplifier
can be used as a comparator. VM can be connected to a

control, using the LTC5532 with a capacitive tap to the
power amplifier. A 0.5pF capacitor (C1) followed by a
200Ω resistor (R1) form a coupling circuit with about
20dB loss at 900MHz referenced to the LTC5532 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.
The LTC5532 can be used as a self-standing signal strength
measuring receiver for a wide range of input signals from
–32dBm to 8dBm for frequencies from 300MHz to 7GHz.
The LTC5532 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 LTC5532 can be configured as a comparator for RF
power detection and RF power alarms. The characterization data includes a plot of the LTC5532 output delay in
response to a positive input step of varying RF level.
The LTC5532 can be used for RF power detection and
control. Figure 1 is an example of a transmitter power
