GENERAL DESCRIPTION

pin. Because the output can be used for controller applications,

special attention has been paid to minimize wideband noise. In

this mode, the setpoint control voltage is applied to the VSET

pin.

The ADL5513 is a demodulating logarithmic amplifier, capable

of accurately converting an RF input signal to a corresponding

decibel-scaled output. It employs the progressive compression

technique over a cascaded amplifier chain, each stage of which

is equipped with a detector cell. The device can be used in

either measurement or controller modes. The ADL5513

maintains accurate log conformance for signals greater than 4

GHz. The input dynamic range is typically 80 dB (re: 50 Ω)

with error less than 3 dB. The ADL5513 has 10 ns response

time which enables RF burst detection to a pulse rate of beyond

50 MHz. The device provides unprecedented logarithmic

intercept stability vs. ambient temperature conditions. A supply

of 2.7 V to 5.5 V is required to power the device. Current

consumption is less than 30 mA, and decreases to TBD μA

when the device is disabled.

The feedback loop through an RF amplifier is closed via VOUT,

the output of which regulates the amplifier’s output to a

magnitude corresponding to V^SET. The ADL5513 provides 0 V

to (V^POS− 0.1 V) output capability at the VOUT pin, suitable for

controller applications. As a measurement device, VOUT is

externally connected to VSET to produce an output voltage

VOUT that increases linear-in-dB with RF input signal amplitude.

The logarithmic slope is 20 mV/dB, determined by the VSET

interface. The intercept is -95 dBm (re: 50 Ω, CW input, 900

MHz) using the INHI input. These parameters are very stable

against supply and temperature variations.

The ADL5513 can be configured to provide a control voltage to

a power amplifier or a measurement output from the VOUT
