30 MHz to 4.5 GHz, 45 dB RF Detector Data Sheet ADL5506 FEATURES GENERAL DESCRIPTION Complete RF detector function
The ADL5506 is a complete, low cost subsystem for the
Typical dynamic range: 45 dB
measurement of RF signals in the 30 MHz to 4.5 GHz frequency
Frequency range from 30 MHz to 4.5 GHz
range, with a typical dynamic range of 45 dB, intended for use
Excellent temperature stability
in a wide variety of wireless terminal devices. It provides a wider
Stable linear in decibel response
dynamic range and better accuracy than is possible using
Power on/off response time: 65 ns/145 ns (rise/fall)
discrete diode detectors. In particular, its temperature stability
−5 dBm input power applied
is excellent over −40°C to +85°C.
Operates from −40°C to +85°C
Its high sensitivity allows measurement of low power levels, thus
Low power: 3.8 mA at 3.0 V
reducing the amount of power that needs to be coupled to the
Power supply voltage range from 2.5 V to 5.5 V
detector. It is essentially a voltage responding device, with a
Disable current <1 μA
typical dynamic range of 45 dB.
APPLICATIONS
For convenience, the signal is internally ac-coupled, using a
RSSI and TSSI for wireless terminal devices
5 pF capacitor and a broadband 50 Ω match, with an external
RF transmitter or receiver power measurement
shunt resistor of 52 Ω. This high-pass coupling, with a corner at approximately 19 MHz, determines the lowest operating frequency. Therefore, the source can be dc grounded. The ADL5506 output increases from approximately 0.14 V to a little over 1 V as the input signal level increases from 1.25 mV rms (−45 dBm) to 224 mV rms (0 dBm). The output is proportional to the logarithm of the input power level; that is, the reading is presented directly in decibels and is scaled about 18 mV/dB at 900 MHz. A capacitor can be connected between the VLOG pin and the CFLT pin when it is desirable to increase the time interval over which averaging of the input waveform occurs. The ADL5506 is available in a 6-ball WLCSP and consumes 3.8 mA from a 3.0 V supply. When powered down, the typical disable supply current is <1 μA.
