2MHz to 1.6GHz 45dB RF-Detecting
Controllers and RF Detector
General Description
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.
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.
