HMC602LP4 / 602LP4E

General Description

Features

Functional Diagram

The HMC602LP4(E) Logarithmic Detector/Controller

converts RF signals at its input, to a proportional DC

voltage at its output. The HMC602LP4(E) employs

a successive compression topology which delivers

extremely high dynamic range and conversion accuracy

over a wide input frequency range. As the input power

is increased, successive ampli ers move into saturation

one by one creating an accurate approximation of the

logarithm function. The output of a series of square law

detectors is summed, converted into voltage domain

and buffered to drive the LOGOUT output. For detection

mode, the LOGOUT pin is shorted to the VSET input,

and will provide a nominal logarithmic slope of -25mV/

dB and an intercept of 12 dBm (19 dBm for ƒ ≥ 5.8 GHz).

The HMC602LP4(E) can also be used in the controller

mode where an external voltage is applied to the VSET

pin, to create an AGC or APC feedback loop.

Wide Dynamic Range: up to 70 dB

High Accuracy: ±1 dB with 60 dB Range Up To 6 GHz

Fast: 8ns Output Response Time

Supply Voltage: +5V

Power-Down Mode

Excellent Stability over Temperature

Buffered Temperature Sensor Output

Compact 4x4mm Leadless SMT Package

Typical Applications

The HMC602LP4(E) is ideal for IF and RF applica-

tions in:

• Cellular/PCS/3G

• WiMAX, WiBro, WLAN, Fixed Wireless & Radar

• Power Monitoring & Control Circuitry

• Receiver Signal Strength Indication (RSSI)

• Automatic Gain & Power Control

Application & Evaluation PCB Schematic

Notes

Note 1: The HMC602LP4 & HMC602LP4E evaluation boards are pre-assembled for single-ended input, and detector/RSSI mode.

Note 2: For detector mode, connect high impedance volt meter to the LOGOUT port, and make no connection to VSET. LOGOUT

is shorted to VSET by R9, as required for detector mode.

Note 3: For controller mode, remove R9 and install 0 ohm resistor (R11), then make appropriate connection to LOGOUT and VSET.

In controller mode, the LOGOUT output can be used to drive a variable gain ampli er, or a variable attenuator, either

directly or through a buffer or microcontroller. VSET should be connected to an external supply, typically between +0.6

and +1.9V.

Note 4: Terminal CPB must be connected to ground for proper operation.

Evaluation PCB

The circuit board used in the  nal application should

use RF circuit design techniques. Signal lines

should have 50 ohm impedance while the package

ground leads and exposed paddle should be con-

nected directly to the ground plane similar to that

shown. A suf cient number of via holes should be

used to connect the top and bottom ground planes.

The evaluation circuit board shown is available from

Hittite upon request.
