Module description
：

• ADL5511 is an RF envelope and TruPwr root mean square detector. Envelope output voltage
  . It is a voltage proportional to the envelope of the input signal. RMS output voltage and input signal
  . The peak-to-average ratio is irrelevant. The rms output is a linear V/V voltage, and the conversion increase at 900 MHz
  . The benefit is 1.9 V/V root mean square value. The conversion gain of the envelope output is 1.46 V/V (900 MHz),
  It is based on the 1.1 V internal reference voltage provided by the ERER pin.

• The ADL5511 can work with signals from DC to 6 GHz, with an envelope bandwidth of up to 130 MHz
  The acquired envelope can be used for RF power amplifier (PA) linearization and efficiency enhancement, mean square
  The root output can be used to measure the root mean square power. High rms accuracy and fast envelope response
  Particularly suitable for broadband peak averages used in CDMA2000, W-CDMA and LTE systems
  Perform envelope detection and power measurement than the signal.

Interface diagram:Dimensions:Precautions :

(1) The maximum input power of the detector module is +20dBm, and the dynamic range of the detector is 47dB.

(2) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a cable

Sexual power supply.

(3) It is recommended to use SMA interface for input signal, poor contact or poor quality wire may cause

Signal attenuation or excessive noise makes the measurement inaccurate.

(4) The response and dynamic range of the detector module at different frequencies will be different.

There are also differences between blocks, which are normal and not a module problem

Test chart:

• Blue is the modulation signal input

• Yellow is the envelope detection output

• Red is the effective value detection output

common problem :

Q: Why is the output not DC when doing RMS detection?

A: First check whether the output port is connected, and then the RMS filter corner frequency (default 40Hz) and

The capacitance of the FLT pin is related and can be modified according to the data.

Q: Why does the output carry some carrier frequencies when doing envelope detection?

A: First check whether the output port is connected, and secondly, the envelope detection corner frequency and FLT pin

The capacitance is related, the default 10MHz module is shipped, the user can modify it according to the data.

Q: I bought 2 modules, and the output voltage of the same test condition is different. Is it normal?

A: There are individual differences between the modules. The detailed measured graphs are typical data, and the specific parameters are based on actual data.

The measurement shall prevail.
