Mercury X32G disassembly, and TP-LINK XDR3230 what is the difference?

Mercury X32G disassembly, and TP-LINK XDR3230 what is the difference?

The actual price of $45, the outer box is relatively thick, thicker than any Mercury router previously bought one:

Do not do a little thicker, 8 antennas are not well placed:

Nearly $45 for a wireless router without a distribution cable is a bit of an understatement.

Fortunately, the power supply is rated output power to give: 12V/2A, to my taste.

Mercury X32G shell is used Mercury D268G:

So many antennas, not everyone can stand, especially those with dense phobia of friends.

I will mark each antenna corresponding to 2.4G or 5G. 2.4G and 5G antennas correspond to the following chart.

Four Gigabit network ports on the back.

I always do not like to support the blind plug network port, like to use different colors to distinguish the WAN port. New machine through the power, I will first plug the computer network cable, into the settings to fix the WAN port, and then plug the modem network cable to the WAN port, so as to reduce the trouble. If you have any instability in the use, there are dropped disconnections, what do not feel right experience, it is recommended to WAN settings to fix the WAN port to use.

Nowadays, computers are used less and less, the router only needs to insert a network cable connected to the modem, blind plug is very practical. If a friend bought a new wireless router, call you and ask which port to insert? You can say: whatever!

Fold open.

The motherboard is very similar to TP-LINK’s XDR3230.

Look at it another way.

The 16V 1000 microfarads capacitor is followed by the 16V 470 microfarads, and there are three 470’s in total.

Eight antennas are welded on the motherboard, flip the motherboard to see the back to be very careful: the

The lower left corner of the back is a flat aluminum plate, positioned at the back of the four 2.4G FEM chips to help FEM heat dissipation, why not in the front of the FEM chip to help heat dissipation? Because some FEM chips can not be put in front of the thermal grease to help dissipate heat, will affect the power of the amplifier. This is what someone said in the message. I do not know if it is true. But I dismantled so many machines, indeed found that many are this way.

There is a flash memory chip above the heatsink, the model is EN25QH128A-104HIP, capacity 16MB.

Remove the heat sink from the front of the motherboard.

Removing the shield, four of the chips, except for the memory chip, have thermally conductive silicone pads.

First look at the CPU, the model is MT7622, dual-band 1.35GHz, and is ARM® Cortex-A53 architecture, stronger than the MT7621, how much stronger do not know! Just know that strong. But one thing is not as good as the MT7621: only integrated five-port 100 megabit switch chip, so it needs an external gigabit switch chip. It is suffering, in order to make the chip space can put the MT7615N, so the MT7622B integrated 4x4mimo 2.4G, support 256-QAM, 802.11n, the highest rate of 800Mbps.

MT7622

Next to the CPU there is a memory chip, model M15T2G16128A, with a capacity of 256MB.

CPU integrated 4T4R 2.4G, external four independent FEM chip, silk-screened “7626H”, the model is RTC7626H (LSI Electronics).

RTC7626

The parameters of the RTC7626H are as follows.

Frequency range: 2.4 – 2.5 GHz
3 V to 5 V single supply voltage
Integrated high performance PA, LNA with bypass function, and SP3T switch
Input & output fully 50 ohm matching
Integrated positive slope power detector
+21 dBm linear output power at 3% EVM, 802.11g 64 QAM, 54 Mbps, 5 V
Small 16L QFN 2.5×2.5×0.75 mm 3 package
RoHS / Halogen Free Compliant
Moisture Sensitivity Level : MSL 3

FEM chip circuit specific.

RTK7626H

Above the CPU is a gigabit switch chip, model RTL8367S, without which there would be no gigabit rate network port.

RTL8367S

Here is a power management chip, model MT6380, MEDIATEK’s own products.

MT6380

Finally, look at the 5G wireless chip, consisting of two chips, as follows: the left chip model is MT7975AN, the right chip model is MT7911AN, together constitute the “MT7915A”. Support 4x4mimo 5G WIFI6, in 80MHz bandwidth, the maximum rate of 2402Mbps, does not support 160MHz bandwidth.

MT7915A

5G does not have an external independent FEM chip, the actual test 5G signal is not bad, similar to the XDR3230.

MT7915A

So far the Mercury X32G disassembly is complete. Chip summary diagram.

The Mercury X32G chip is exactly the same as TP’s XDR3230, and the memory flash capacity is also the same, unless there is no difference in appearance and price.
