EVALUATION KIT AVAILABLE

MAX9930–MAX9933

2MHz to 1.6GHz 45dB RF-Detecting

Controllers and RF Detector

General Description

Features

●

The MAX9930–MAX9933 low-cost, low-power logarithmic

amplifiers are designed to control RF power amplifiers

(PA) and transimpedance amplifiers (TIA), and to detect

RF power levels. These devices are designed to operate

in the 2MHz to 1.6GHz frequency range. A typical dynam-

ic range of 45dB makes this family of logarithmic ampli-

fiers useful in a variety of wireless and GPON fiber video

applications such as transmitter power measurement, and

RSSI for terminal devices. Logarithmic amplifiers provide

much wider measurement range and superior accuracy to

controllers based on diode detectors. Excellent tempera-

ture stability is achieved over the full operating range of

-40°C to +85°C.

Complete RF Detector (MAX9933)

Variety of Input Ranges

MAX9930/MAX9933: -58dBV to -13dBV

(-45dBm to 0dBm for 50Ω Termination)

MAX9931: -48dBV to -3dBV

(-35dBm to +10dBm for 50Ω Termination)

MAX9932: -43dBV to +2dBV

(-30dBm to +15dBm for 50Ω Termination)

2MHz to 1.6GHz Frequency Range

Temperature Stable Linear-in-dB Response

Fast Response: 70ns 10dB Step

10mA Output Sourcing Capability

Low Power: 17mW at 3V (typ)

The choice of three different input voltage ranges elimi-

nates the need for external attenuators, thus simplifying

PA control-loop design. The logarithmic amplifier is a

voltage-measuring device with a typical signal range of

-58dBV to -13dBV for the MAX9930/MAX9933, -48dBV

to -3dBV for the MAX9931, and -43dBV to +2dBV for the

MAX9932.

13μA (typ) Shutdown Current

Available in a Small 8-Pin μMAX Package

The MAX9930–MAX9933 require an external coupling

capacitor in series with the RF input port. These devices

feature a power-on delay when coming out of shutdown,

holding OUT low for approximately 2.5μs to ensure

glitch-free controller output.

The MAX9930–MAX9933 family is available in an 8-pin

8 µMAX

μMAX package. These devices consume 7mA with a

8 µMAX

5V supply, and when powered down, the typical shut-

down current is 13μA.
