Figure 1 shows the functional diagram for the MAX3761/

MAX3762. The input signal is applied to VIN+ and VIN-.

A chain of amplifier stages, each contributing approxi-

mately 12.5dB of gain, amplifies the input signal to

PECL output voltage swings. A 4mVp-p input signal will

cause the output to fully limit.

ance at the FILTER pin is approximately 500Ω.

The FILTER capacitor (C

) must be connected

FILTER

to V

for proper operation.

Input-Offset Correction

The limiting amplifier provides approximately 60dB of

gain. An input DC offset of even 1mV reduces the

power-detection circuit’s accuracy and can cause the

output to limit. A low-frequency feedback loop is inte-

grated into the MAX3761/MAX3762 to remove input off-

set. DC coupling the inputs is not recommended, as

this prevents the DC-offset-correction circuitry from

functioning properly. Input offset is typically reduced to

less than 100μV.

Received-Signal-Strength

Indicator (RSSI)

Each amplifier stage contains a full-wave logarithmic

detector (FWD). The full-wave detector outputs are

summed at the FILTER pin and used to generate the

received-signal-strength indication (RSSI). The RSSI

output voltage is linearly proportional to the input power

(in decibels), and is approximated by:

The capacitance between pins CZP and CZN, in parallel

with a 10pF integrated capacitance, determines the off-

set-correction circuit’s time constant. The input imped-

ance between CZP and CZN is approximately 800kΩ.

The offset correction circuitry requires an average data-

input duty cycle of 50%. If the input data has a different

average duty cycle, the output will have increased

pulse-width distortion.

(V) = 1.13 + 0.457log (V )

RSSI

where V is the peak-to-peak input signal in millivolts.

The RSSI output is insensitive to fluctuations in temperature

and supply voltage. The power detector functions as a

broadband power meter that detects the total power of all

signals present in the passband of approximately 750MHz.

Refer to the Typical Operating Characteristics graphs show-

ing RSSI output versus input power and signal amplitude.
