1.2 withnew block 70. block 40/50 has 4mOnly with a small percent 1 to 1.2.
1-Rafale at min can have 0.4 clean (SuperHornet has 0.1 to 1 Sqm when clean and keep in mind SH has more stealth measures)why not ?
GaN modules should give the capability to take the full advantage of meteor.I don't think a bigger AESA can be fit in that nose? RBE2 has 838 GaAs T/R modules. The best that can be done is probably to switch to a similarly sized GaN AESA. BTW neither RBE2 nor APG-83 SABR have necessary capabilities to fully take advantage of Meteor missile.
Surprise surprise MURAD is also GaNGaN modules should give the capability to take full advantage.
Block30/40/50 with HaveGlass applied have lower RCS, tho it depends on the model applied1.2 withnew block 70. block 40/50 has 4m
and i think rafales more accurate rcs is 0.5.
i think somebody in this thread said GaN modules require 2x more power for cooling! do you know where is that post ?Surprise surprise MURAD is also GaN
I think 2-3 pages before, and this is a disadvantage for Rafale, smaller nose, smaller space left for coolingi think somebody in this thread said GaN modules require 2x more power for cooling! do you know where is that post ?
GaN modules can resist to heat more than GaAs but eventually overheating makes them dye,so it would not to be cost effectiveI think 2-3 pages before, and this is a disadvantage for Rafale, smaller nose, smaller space left for cooling
found it, it is in @rodeo post,I think 2-3 pages before, and this is a disadvantage for Rafale, smaller nose, smaller space left for cooling
I am not sure about that, Greek article about AN/APG-80 and APG-83 didn't mention they were electrical power but thermal generationfound it, it is in @rodeo post,

It's true that power density of GaN modules are like 5-10 times that of GaAs but they require equally more cooling. That's why ASELSAN had to develop a liquid cooled system. With AESA radars you need about two times more power for the cooling system than the T/R module consumes. If say a module needs 20 watts of power for operation, you need to supply the cooling system with 40 watts. However your GaN radar has %50 more range than a similar sized GaAs radar. The trade-off is worth it.

even though i coudnt verify it independently but if it is the case, than do you see the problem with MURAD here?
as you mentioned previously, f16 produce up to 60kw.
so doesnt it seems then, MURAD wouldnt be able to operate more than 60 percent of its actual capability! likely around 15kw/17kw.
@Yasar what is your opinion on that ?
I should add my reference too.found it, it is in @rodeo post,

As I mentioned, the cooling power we need is not electrical but thermal, think of it like thermal generation in nuclear plantsWell, block 52/72 uses pw f100 which generate 76kw.
True. Air cooling maxes at 2.3 kW per square meter. Liquid cooling is different though.Gan T/R modules is smaller than GaAS ,even on the same nose the improvement will be huge,but small surface with more power make a huge challenge for heating problems versus large surface.
If anyone ınterested you can use Scihub to access research papers.True. Air cooling maxes at 2.3 kW per square meter. Liquid cooling is different though.
Special cooling system designed by Aselsan for GaN MMICs. It is behind the paywall you can read the abstract.
Numerical Study of Multi Hot Spot GaN Cooling in a Cold Plate Considering Different Flow Networks
As electronic technology develops continuously, space and power allocated for cooling demands increase with time. Therefore, it becomes necessary to develop effective approaches to decrease the cooling power spent and allocated space to obtain low SWAP (Size Weight and Power) values.

It is getting a bit repetitive and boring to hear “ ours has superior capabilities compared to it’s counterparts” statements for every new piece of equipment we make.A very ambitious statement about two very serious products came from the Turkish officials. Both systems are game changers in air superiority.
First, MURAD AESA radar powered by GaN-based ABmicronano transistors will be superior than APG-83.
The second explanation is that the Gokhan missile will have superior capabilities than its counterparts.
by tilting the radar at an angle, theoretically they could increase the no. of TR modulesI don't think a bigger AESA can be fit in that nose? RBE2 has 838 GaAs T/R modules. The best that can be done is probably to switch to a similarly sized GaN AESA. BTW neither RBE2 nor APG-83 SABR have necessary capabilities to fully take advantage of Meteor missile.
Tilting is not done for more TR modules, it is done for stealthby tilting the radar at an angle, theoretically they could increase the no. of TR modules

the question of whether the Rafale's engines would be able to generate power for a more power consuming radar is there.
