ADL5350 and ADL5801 - Up Converson Linearity Does any data show the the linearity (IP3 for example) when mixers are used in Up Conversion mode?
RF = 1710MHz - 1920 MHz LO = 685 MHz IF = 2395MHz - 2605MHz
I don't think either ADL5350 or ALD5801 has been characterized for the frequency plan you mentioned. However, I would expect the input IP3 out of both mixers might be very similar, around 25dBm, for this application. Thanks to its adjustable VSET bias, you should have good chance to get slightly better IP3 with ADL5801 by tuning the VSET voltage to the right value.
Looking at the bigger picture, you shopped for two completely different type of mixes here: a single-ended passive mixer (ADL5350) and a differential active mixer (ADL5801). They each have their own advantages you probably need to consider:
Gain: ADL5801 offers 0dB power gain, while ADL5350 has typically 7dB conversion loss.
Noise Figure: Passive mixers like ADL5350 are known for lower noise.
Isolation: ADL5801 has clear advantages if you compare spur tables on data sheets.
Supply Current: ADL5350 only runs 20mA or under, while the active mixer demands more power.
Attached has two up conversion examples of ADL5350 and ADL5801. I hope they are helpful.
A Rev A version of the ADL5801 datasheet is soon to be released. This will include typical data in several new bands of interest in both Upconversion and Downconversion mode. Data for Upconversion Bands centered around 900MHz and 2140MHz will be featured in this revision as follows:
RF 153MHz, LO 453MHz - 1453MHz, IF 300MHz - 1300MHz
RF 170MHz, LO 2070MHz - 2870MHz, IF 1900MHz - 2700MHz
Could you please provide the S-parameters file of the ADL5350 Mixer?
Thanks in advance.
We do not support S-parameters for ADL5350. The passive mixer core is essentially a FET switch. Any attempt of measuring device S-parameters would result looking at the on/off switching impedance, which is not useful for external matching/filtering designs. It is the best to follow the implementation procedure on ADL5350 data sheet, and optimize the external networks for the desired frequency plan. There are also some examples in the data sheet that can be used as starting points of your tuning practice.
