Hello, I have a question about bias sequencing problem of ADRF5045.
From the data sheet, ADRF5045 bias sequencing follows 1. GND, 2. VDD, 3. VSS, 4. control voltage before the input.
And i simply followed the sequencing, but the components keep dying…
Hi,
Do you have any information with regards to rise and fall time?
The mask Margin is very less when check on Evaluation board .
Thanking you
With best regards and wishes
Dear Analog,
i'm using ADRF5045 for a tunable filter bank prototype.
in the datasheet i have seen that every output of the SP4T is DC coupled.
is it dc coupled to 0V?
i need to connect a diode varactor at the ouput of every channel (SP4T) and for…
我公司预使用ADI两个开关产品，一组：ADRF5044/ADRF5045 二选一；二组：ADRF5020/ADRF5021二选一；现想咨询一组和二组开关可否级联使用？谢谢
Hi BrendanT,
I see you have DC blocking caps on the RF lines connecting this block to the previous and next block.
The RF ports are DC coupled to 0V and these connect to the drain/source of the RF transistors. As long as your control signals are clean…

You need a PLL which drives a frequency doubler which drives an amplifier. Possible choices might be ADF4371 (PLL), HMC1105 (frequency doubler) and HMC7229 (amplifier). These are not the only choices.
