2MHz to 1.6GHz 45dB RF-Detecting
Controllers and RF Detector
General Description
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.
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.
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
μMAX® package. These devices consume 7mA with a
5V supply, and when powered down, the typical shut-
down current is 13μA.
Applications
RSSI for Fiber Modules, GPON-CATV Triplexors
Low-Frequency RF OOK and ASK Applications
Transmitter Power Measurement and Control
TSI for Wireless Terminal Devices
Cellular Handsets (TDMA, CDMA, GPRS, GSM)
