GENERAL DESCRIPTION

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 up to 4 GHz. The input

dynamic range is typically 80 dB (referred to 50 Ω) with error less

than 3 dB and 74 dB with error less than 1 dB. The ADL5513

has 20 ns response time that 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 31 mA, and it decreases to 200 μA when the

device is disabled.

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

the output of which regulates the amplifier output to a magni-

tude corresponding to VSET. 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,

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

The logarithmic slope is 21 mV/dB, determined by the VSET

interface. The intercept is −88 dBm (referred to 50 Ω, conti-

nuous wave input, 900 MHz) using the INHI input. These

parameters are very stable against supply and temperature

variations.

The ADL5513 is fabricated on a SiGe bipolar IC process and

is available in a 3 mm × 3 mm, 16-lead LFCSP package for the

−40°C to +125°C operating temperature range. A fully populated

evaluation board is available.

The ADL5513 can be configured to provide a control voltage to

a power amplifier or a measurement output from the VOUT 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.
