2MHz to 1.6GHz 45dB RF-Detecting

Controllers and RF Detector

0–MAX93

General Description

Features

o Complete RF-Detecting PA Controllers

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

mic amplifiers are designed to control RF power ampli-

fiers (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 typi-

cal dynamic range of 45dB makes this family of logarith-

mic amplifiers useful in a variety of wireless and GPON

fiber video applications such as transmitter power mea-

surement, and RSSI for terminal devices. Logarithmic

amplifiers provide much wider measurement range and

superior accuracy to controllers based on diode detec-

tors. Excellent temperature stability is achieved over the

full operating range of -40°C to +85°C.

(MAX9930/MAX9931/MAX9932)

o Complete RF Detector (MAX9933)

o 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)

o 2MHz to 1.6GHz Frequency Range

o Temperature Stable Linear-in-dB Response

o Fast Response: 70ns 10dB Step

o 10mA Output Sourcing Capability

o 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.

o 13µA (typ) Shutdown Current

o 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.

CODE

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

µMAX^®package. These devices consume 7mA with a

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

down current is 13µA.
