The LTC
®
5535 is an RF power detector for RF applications
operating in the 600MHz to 7GHz range. A temperature
compensated Schottky diode peak detector and output
amplifier are combined in a small ThinSOT
TM
package. The
supply voltage range is optimized for operation from a
single cell lithium-ion or three cell NiMH battery.
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 LTC5535 output amplifier gain is set via external
resistors. The initial starting voltage of 200mV can be
precisely adjusted using the V
OS
pin.
The LTC5535 operates with input power levels from
–32dBm to 10dBm. The 12MHz baseband bandwidth is
much higher than that of previous Schottky detector
products.

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 V
OUT
is measured between 1.3V and 2.3V.
Note 4: See Table 1 in Applications Information section.
Note 5: RF performance is tested at 1800MHz
Note 6: Guaranteed by design.

Operation
The LTC5535 RF detector integrates several functions to
provide RF power detection over frequencies ranging
from 600MHz to 7GHz. These functions include an internal
frequency compensated output amplifier, an RF Schottky
diode peak detector and a level shift amplifier to convert the
RF input signal to DC. The LTC5535 has both gain setting
and voltage offset adjustment capabilities.
Output Amplifier
The output amplifier is capable of supplying typically
20mA into a load. The negative terminal V
M
is brought out
to a pin for gain selection. External resistors connected
between V
OUT
and V
M
(R
A
) and V
M
to ground (R
B
) will set
the gain of this amplifier.
Gain = 1 + R
A
/R
B
The amplifier is not unity gain stable; a minimum gain of
two is required. The output amplifier has a bandwidth of
20MHz with a gain of 2. For increased gain applications,
the bandwidth is reduced according to the formula:
Bandwidth = 40MHz/(Gain) = 40MHz • R
B
/(R
A
+ R
B
)
For stable operation the gain setting resistors should be
low values and the board capacitance on V
M
should be
minimized. R
B
is recommended to be no greater than
500 for all gain settings.
The V
OS
input controls the DC input voltage to the output
amplifier. V
OS
must be connected to ground if the DC
output voltage is not to be changed. The output amplifier
is initially trimmed to 200mV (Gain = 2) with V
OS
con-
nected to ground.
The V
OS
pin is used to change the initial V
OUT
starting
voltage. This function, in combination with gain adjust-
ment enables the LTC5535 output to span the input range
of a variety of analog-to-digital converters. V
OUT
will not
change until V
OS
exceeds 200mV. The starting voltage at
V
OUT
for V
OS
>200mV is:
V
OUT
= 0.5 • V
OS
• Gain
where gain is the output amplifier gain. For a gain of 2,
V
OUT
will exactly track V
OS
above 200mV.
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 50µA and drives a
5pF internal peak detector capacitor.

Applications
The LTC5535 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 600MHz to 7GHz.
The LTC5535 offers increased baseband bandwidth com-
pared to other Schottky diode detectors. Table 1 shows
that the baseband (demodulation) bandwidth is typically
12MHz at an RF input signal level of –10dBm. The baseband
bandwidth is largely independent of the RF input signal
frequency over the range of 600MHz to 7GHz.

–5 11 3 2

Operation at higher RF input frequencies is achievable.
Consult factory for more information.
The LTC5535 can be used as a demodulator for AM and
ASK modulated signals. Depending on specific application
needs, the RSSI output can be split between two branches,
providing AC-coupled data (or audio) output and a
DC-coupled RSSI output for signal strength measure-
ments and AGC.
