How can I avoid startup transients when operating the AD8318 in Controller Mode? I am using the AD8318 Log Detector/Controller to control the output level in an AGC loop. The control loop consists of a fixed-gain RF amplifier, an ADL5330 VGA, a…
Is there impedance data available for the ADL5330 VGA?
We are using in the front end of a 450 MHZ radar system
You could try AD8317 for the detector, which also supports controller mode. See datasheet page 13 and Figure 30. You will need a VGA with wider frequency range than ADL5330 can support.
Thanks for your inquiry. We have other VGA and Detector products that may work for your application. A couple of analog devices that may apply are: ADL5330 analog VGA and a log detector, AD8318 . Details are available on Analog.com. See also…
I used ADL5330 and AD8318 to configure AGC Loop.
The circuit is same as Fig37 in page16 of ADL5330 spec.
In CW mode, it works perfect.
I have a question, if I want to use it in pulse mode.
Carrier is 500M, the pulse width is 100ms…
About ADL5330,hot swiching (on/off control) of the ENBL pin is available with the RF signal input @-10dBm ?
Could I have the BOM list of ADL5330 evaluation board?
Especially, I want to know coil vendor and parts# of L1A, and L2A .
The three SMA connectors shoudl be left open.
