The response time from the RF input to VOUT can be as little
as 20ns. The comparator output is latched when LEN is
high or is transparent when LEN is low.

The RF input voltage is peak detected using an on-chip
Schottky diode. The detected voltage is compared against
a reference voltage at VM.

APPLICATIO S I FOR ATIO
Operation
The LTC5536 is configured as a fast detector and high
speed comparator for RF power detection and RF power
alarms. The product integrates several functions to provide RF power detection over frequencies ranging from
600MHz to 7GHz. These functions include an RF Schottky
diode peak detector, a level shift amplifier to convert the RF
input signal to low frequency, and a fast comparator. The
LTC5536 provides a comparator reference input VM and a
latch enable input LEN.
RF Detector
The internal RF Schottky diode peak detector and level
shift amplifier convert 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 15pF
internal peak detector capacitor.
High Speed Comparator
The fast internal comparator compares the external reference voltage at VM to the internal signal voltage from the
peak detector, and produces the output signal, VOUT. The
internal peak detector voltage is factory trimmed to 100mV
with no RF signal present. The comparator has approximately 10mV of hysteresis, with a typical VOUT low-to-high
switching point of 100mV and a VOUT high-to-low switching point of 90mV with no RF signal present.
The comparator also has a built-in latch. This will cause the
VOUT output to latch high on a positive comparator transition (increasing RF power), when the LEN pin is high, as
indicated in the waveforms of Figure 1. For transparent

operation of the comparator (no latching action), the LEN
pin should be connected to ground.
The comparator output (VOUT) rise and fall times are
approximately 2ns (unloaded). The propagation delay for
the comparator alone was characterized by applying a
continuous 2GHz RF signal to the RFIN input. Then a 1MHz
square wave (0V to 2.5V) was applied to the VM input to
switch the comparator. Note that there is a signal inversion, because the VM pin is connected internally to the
negative comparator input. The time delay from the transition edge of the square wave at the VM input to the
corresponding VOUT output transition (rising or falling) is
shown in Table 1.

Overall Propagation Delay and Response Time
Figure 2 shows measurements of total propagation delay
from the RFIN signal input to the VOUT output of the
LTC5536, plotted as a function of RF input power. The
response is shown for RF Signal Absent-to-RF Signal
Present Transitions (Rising Edge VOUT), and for RF Signal
Present-to-RF Signal Absent Transitions (Falling Edge
VOUT). The LTC5536’s RF detector is optimized as a
positive peak detector. Consequently, the device responds
to a rising signal at the RF input much more rapidly than
to a falling signal. Correspondingly, Rising Edge VOUT
transitions are much more rapid than Falling Edge transitions, as shown in Figure 2. The minimum propagation
delay is about 20ns at room temperature, in response to
strong overdrive conditions at the RFIN input. These
results were measured by applying a 1GHz RF signal that
was amplitude modulated by a 1MHz square wave with
50% duty cycle. An example time domain waveform is
shown in Figure 3.

Higher Frequency Operation
as a 100pF ceramic, is recommended, in parallel with a
larger capacitor (e.g., 0.1µF).
Operation of the LTC5536 at higher frequencies, to 12GHz
or above, is possible with reduced performance. Figure 4
plots the VM switching voltage vs RFIN input power with a
12GHz RF input. Consult factory for more information.
High Speed Design Techniques
Avoid ground bounce problems by proper attention to
grounding, including the use of a low impedance ground
plane. If necessary, edge transition time at the comparator
output, VOUT, may be increased by means of an output
R-C low pass filter.
As with all high speed comparators, careful attention to
printed circuit board layout and design is important in
order to ensure signal integrity. The most common problem involves insufficient power supply bypassing. Bypass
capacitors should be placed as close as possible to the
LTC5536 VCC pin. A good high frequency capacitor, such
Poor trace routes and high source impedances are also
common sources of problems. Keep all trace lengths as
short as possible and avoid running the output trace close
to the VM or the LEN traces on the PC board. Also, keep the
VM source impedance low and decouple the VM pin with an
appropriate capacitor if necessary.
